Time datalist "Other" popup above anchor

What this sampler checks

Manual repro

Expected vs actual

This page forces an <input type="time" list="..."> control to the bottom of the viewport so Chromium's suggestion popup opens above the control. Click the popup's Other row.

Expected: the time picker opens so a custom time can be chosen.
Windows 11 affected builds: the suggestion popup hides, but the time picker does not open. Some builds show a tiny dot or shadow.
Linux and macOS are useful controls. They are not expected to show the Windows-only native failure.
The edge-case sampler also covers the old date suggestion picker Other path and a datetime-local control.

Live repro

Steps

Click Pin repro input to viewport bottom.
Click Open bottom picker.
In the native suggestion popup, click Other.
On a good build, the full time picker opens. On affected Windows builds, it does not.

Optional screen capture

DOM screenshots do not include Chromium's native picker popup. This helper uses the browser's screen-capture prompt, then stores the latest captured frame while you reproduce the issue. Select the whole screen or browser window if the prompt asks what to share.
