[Copilot]

On Android Chrome, double-tapping a word after a thought has been multiselected and then deselected is reported to select the word and show the Translate / Cut / Copy menu, but no selection handles.

This PR contains no code changes yet. The bug did not reproduce on main (e1af1e0, the build the issue was filed against), so no cause has been identified and no fix or regression test has been written.

Reproduction attempts

All runs used real-device Chrome 152 on BrowserStack, with taps sent as native device touches rather than synthetic events. Handles were detected in device screenshots.

Device	Content	Handles after the double tap
Pixel 8, Android 14	- Lorem ipsum dolor sit amet	Both shown (3 double-tap timings)
Galaxy S24, Android 14	Same thought	Both shown (long press on Lorem and on dolor; 400 ms and 1500 ms between steps)
Galaxy S24, Android 14	The three nested, multi-line thoughts from the issue screenshot	Both shown
Galaxy S25, Android 15	- Lorem ipsum dolor sit amet	Both shown

Every intermediate step behaved as the issue describes:

1. The first tap put a caret in dolor and opened the keyboard.
2. The long press selected the thought.
3. Tapping empty space cleared that selection.
4. The double tap selected dolor.

Differences from the reporter's run

• Keyboard: the issue screenshot shows Samsung Keyboard. The test devices probably used a different keyboard, and it can't be changed on BrowserStack.
• Gesture timing: a human finger may differ from the scripted touches.

Needed to proceed

• The reporter's phone model, Android version and Chrome version.
• Whether the bug happens every time.
• A Debug Log captured from a failing run.
