It did not, however,\nhelp bare codepoints whose Unicode `Emoji_Presentation` property is\nalready Yes (e.g. U+1F004 MAHJONG TILE RED DRAGON, U+1F3B2 GAME DIE,\nthe U+1F000-U+1F02F Mahjong / Domino / Playing-Card block), because\nthey carry no VS-16 and so never entered the new pre-pass.\n\nOn macOS those default-emoji codepoints already render in color via\nCoreText's cascade list. On Windows they do not: gfx::RenderText's\nGetFallbackFont path returns Segoe UI Symbol (which provides a\nmonochrome glyph for the same codepoint) instead of Segoe UI Emoji,\nso shaping succeeds against a text font and the run never reaches a\ncolor fallback. The visible result was the same canary build showing\n\"\\U0001F004\" as monochrome in a Windows tab title and color in the\nmatching macOS tab title.\n\nFix: extend RunRequestsEmojiPresentation() to also return true when\nthe run contains any codepoint with `Emoji_Presentation=Yes`, in\naddition to the existing VS-16 check. The emoji pre-pass in\nShapeRuns then routes such runs through the platform color emoji\nfont, mirroring what macOS does at the OS level and what Blink does\nin Web content via FontFallbackPriority::kEmojiEmoji. VS-15 (text\npresentation) continues to take precedence via the existing\nRunRequestsTextPresentation check at the call site, so e.g.\n\"\\U0001F004\\uFE0E\" still renders as text.\n\nIteration uses base::i18n::UTF16CharIterator to handle surrogate\npairs (the relevant codepoints are all \u003e= U+1F000) and to satisfy\n-Wunsafe-buffer-usage.\n\nManual verification on Windows (local dev build vs. Chromium\nCanary): \"\\U0001F004\", \"\\U0001F0CF\", \"\\U0001F3B2\" now render in\ncolor in tab titles, matching the macOS behavior; \"\\u2666\\uFE0F\"\nand other VS-16 sequences continue to render in color as before;\nstrings with VS-15 continue to render as text.\n\nFixed: 519440127, 40137571\nChange-Id: I59c74331e07894e626758e3b4aa35d0d79a96371\nReviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/7897969\nReviewed-by: Mike Wasserman \u003cmsw@chromium.org\u003e\nReviewed-by: David Yeung \u003cdayeung@chromium.org\u003e\nCommit-Queue: Chang Liu \u003cchangliu1@microsoft.com\u003e\nCr-Commit-Position: refs/heads/main@{#1642901}", "email": "changliu1@microsoft.com", "hash": "7680799f7a6dee1223f4e4a79f48ea86cf136b2f" }, "7903702": { "author": "chrome-official-brancher@chops-service-accounts.iam.gserviceaccount.com", "avatar": "https://lh6.googleusercontent.com/-bmjmM3wy1aI/AAAAAAAAAAI/AAAAAAAAAAA/ZO8sFsZRTr4/s120-p/photo.jpg", "description": "* This is an automated release commit.\n* Do not revert without consulting chrome-pmo@google.com.\nNOAUTOREVERT=true\n\nChange-Id: I0029f350e6d2c4903f6b13a7a8761154ed24dcd2\nReviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/7903702\nBot-Commit: chrome-official-brancher@chops-service-accounts.iam.gserviceaccount.com \u003cchrome-official-brancher@chops-service-accounts.iam.gserviceaccount.com\u003e\nCr-Commit-Position: refs/heads/main@{#1642909}", "email": "chrome-official-brancher@chops-service-accounts.iam.gserviceaccount.com", "hash": "e23927ff3fd1df9257fa8f837bba44aef182a598" }, "7905080": { "author": "Chrome Release Translations", "avatar": "https://lh3.googleusercontent.com/-XdUIqdMkCWA/AAAAAAAAAAI/AAAAAAAAAAA/4252rscbv5M/s120/photo.jpg", "description": "Binary-Size: Size increase is unavoidable\nChange-Id: I94e0530e149a33a51dbb953b7d5f53048aab641d\nReviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/7905080\nBot-Commit: rubber-stamper@appspot.gserviceaccount.com \u003crubber-stamper@appspot.gserviceaccount.com\u003e\nCommit-Queue: rubber-stamper@appspot.gserviceaccount.com \u003crubber-stamper@appspot.gserviceaccount.com\u003e\nSLSA-Policy-Verified: SLSA Policy Verification Service \u003cdevtools-gerritcodereview-exitgate@google.com\u003e\nAuto-Submit: Chrome Release Translation Dump \u003cmdb.chrome-release-translation-dump@google.com\u003e\nCr-Commit-Position: refs/heads/main@{#1642911}", "email": "mdb.chrome-release-translation-dump@google.com", "hash": "9dc8ccb8ebd24484f99abd10af2693983c789348" }, "7905883": { "author": "Dominic Austria", "avatar": "https://lh5.googleusercontent.com/-pGKrF0IVeGo/AAAAAAAAAAI/AAAAAAAAAAA/DT7supeRR-4/s120-p/photo.jpg", "description": "Bug: 503332291\nChange-Id: I6c600ad9afc45aace1f6918e572c45d3e7ce2b31\nReviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/7905883\nReviewed-by: Eshwar Stalin \u003cestalin@chromium.org\u003e\nCommit-Queue: Dominic Austria \u003cdominicaustria@google.com\u003e\nCr-Commit-Position: refs/heads/main@{#1642927}", "email": "dominicaustria@google.com", "hash": "f9205584d1d00e5f647f17226d78f89799aa401d" }, "7905899": { "author": "rosiey", "avatar": "https://lh6.googleusercontent.com/-7yBUbcAIHXA/AAAAAAAAAAI/AAAAAAAAAAA/7h2u_eYui14/s120-p/photo.jpg", "description": "Currently, tasks in kExperimentalTriggering feature mode auto-show the\ntask nudge and bubble when the task transitions to the kActing state.\nBut because tasks transition from kReflecting at the end of a turn back\nto kActing at the start of a turn on every action/turn, this causes the\nnudge/bubble to pop up repeatedly on every turn.\n\nTo fix this, this CL tracks shown task IDs in a flat_hash_set inside\nGlicActorTaskIconManager, ensuring the nudge is shown only on the first\ntransition to kActing.

[CL 7278838](https://chromium-review.googlesource.com/c/7278838)\n- **Networking** WebTransport stream creation now carries explicit stream priority over Mojo, wiring send group and send order into the network service for finer HTTP/3 scheduling control. [CL 7874382](https://chromium-review.googlesource.com/c/7874382)\n- **UI** The Glow Up reload button animation now fires only on actual button press, avoiding gratuitous motion during state changes and tightening toolbar polish. [CL 7905883](https://chromium-review.googlesource.com/c/7905883)\n- **Rendering** Chromium now prefers the platform color emoji font even for default-emoji codepoints, improving emoji fidelity and consistency in text rendering. [CL 7897969](https://chromium-review.googlesource.com/c/7897969)\n- **Build** Betty trybots are now critical on the default Chrome CQ path, increasing ChromeOS signal before submit and making failures harder to miss. [CL 7867483](https://chromium-review.googlesource.com/c/7867483)\n- **Refactor** Extensions unit tests cleaned up several exit-time destructors, another step toward enabling the warning more broadly without test-only leaks. [CL 7906576](https://chromium-review.googlesource.com/c/7906576)\n- **UI** Glic now shows its experimental triggering nudge only on the first turn, reducing repeated prompting in the AI surface. [CL 7905899](https://chromium-review.googlesource.com/c/7905899)\n\n## What landed by area\n\n### Media and autoplay\n- **Rendering** Blink moved media frame visibility handling into `HTMLMediaElement`, simplifying control flow around hidden playback decisions. [CL 7278838](https://chromium-review.googlesource.com/c/7278838)\n- **Media** The old `RendererWebMediaPlayerDelegate` visibility plumbing was trimmed back, shrinking renderer-side special casing for media visibility. [CL 7278838](https://chromium-review.googlesource.com/c/7278838)\n- **Web Platform** New nested and cross-origin web tests now cover permission-policy behavior for hidden media playback and pause-on-hide. [CL 7278838](https://chromium-review.googlesource.com/c/7278838)\n- **Refactor** Autoplay policy code dropped direct dependencies on the older visibility path, aligning enforcement with the new observer flow. [CL 7278838](https://chromium-review.googlesource.com/c/7278838)\n\n### Networking and WebTransport\n- **Networking** `web_transport.mojom` gained a `WebTransportStreamPriority` struct so stream creation can carry scheduling hints over IPC. [CL 7874382](https://chromium-review.googlesource.com/c/7874382)\n- **Web Platform** Blink's WebTransport implementation now forwards nullable priority data from JS-side stream creation into the network stack. [CL 7874382](https://chromium-review.googlesource.com/c/7874382)\n- **Networking** The network service applies send group and send order through `WebTransportStream::SetPriority()`, making per-stream prioritization real instead of declarative. [CL 7874382](https://chromium-review.googlesource.com/c/7874382)\n- **Refactor** Priority group `0` is now reserved as a sentinel for \"no group\", which cleans up API semantics for default behavior. [CL 7874382](https://chromium-review.googlesource.com/c/7874382)\n- **Networking** WebTransport unit tests and Blink stream tests were updated to lock down the new priority plumbing. [CL 7874382](https://chromium-review.googlesource.com/c/7874382)\n\n### UI and desktop Chrome\n- **UI** Reload button animation now triggers only on press, not on unrelated toolbar state transitions. [CL 7905883](https://chromium-review.googlesource.com/c/7905883)\n- **UI** Reload button unit tests expanded to pin the new animation behavior and avoid regressions during toolbar work. [CL 7905883](https://chromium-review.googlesource.com/c/7905883)\n- **UI** Glic's experimental triggering nudge is now first-turn only, which should make the feature feel less naggy in repeated conversations. [CL 7905899](https://chromium-review.googlesource.com/c/7905899)\n\n### Text and emoji rendering\n- **Rendering** `RenderTextHarfBuzz` now uses the platform color emoji font for default-emoji codepoints too, not just explicitly emoji-presented ones. [CL 7897969](https://chromium-review.googlesource.com/c/7897969)\n- **UI** Text rendering tests were substantially broadened to verify emoji font fallback and presentation behavior across more cases. [CL 7897969](https://chromium-review.googlesource.com/c/7897969)\n\n### Extensions and tests\n- **Refactor** Extensions browser tests removed a few exit-time destructors, reducing shutdown noise and making warning enforcement more tractable. [CL 7906576](https://chromium-review.googlesource.com/c/7906576)\n- **Build** `chrome/browser/extensions/BUILD.gn` was adjusted alongside the cleanup to keep test targets linked correctly after the destructor fixes. [CL 7906576](https://chromium-review.googlesource.com/c/7906576)\n\n### Infra and CQ\n- **Build** Default Chrome CQ now treats Betty bots as critical, raising ChromeOS coverage for regular Chromium submissions. [CL 7867483](https://chromium-review.googlesource.com/c/7867483)\n- **Build** CQ routing now differentiates between external contributors, Googlers, ChromeOS PA, and robot committers for which Betty builder set they must run. [CL 7867483](https://chromium-review.googlesource.com/c/7867483)\n- **Build** Generated CQ configs and builder docs were regenerated to reflect the new Betty criticality and usage rules. [CL 7867483](https://chromium-review.googlesource.com/c/7867483)\n\n## Reverts \u0026 Reapplies\n- **Media** The daily window includes a revert commit for the media visibility refactor, indicating churn around the `HTMLMediaElement` visibility migration.
