ACT "Open in browser" repro

Chromium issue 41495930 / 510460240
display-mode?
this load?
session id?
launch count?
state?
Steps
  1. Confirm display-mode above reads standalone.
  2. Note the session id and this load time.
  3. Tap the button (a cross-origin target="_blank" link) to open the in-app browser (Custom Tab).
  4. In the in-app browser: menu → Open in Chrome.
  5. Return to this PWA (recents or back).
Open example.com (target=_blank)
Expected (fixed): the session id and load time stay the same — the PWA was kept alive in the background.
Bug: the PWA is closed/removed from recents, or cold-reloads with a new session id.
