Please consider the following strategies to mitigate the impact from this issue which are rated in order of resolution preference:
1. Resolve the underlying test issue.
2. Move the flaky test from Critical Builders to FYI Builder
3. Disable test (least desirable as it reduces test coverage) and add a Test-Disabled label to this issue. The disabled tests might continue running in reviver builders (go/test-reviver), see config [1] for a list of supported builders.

Tried testing the issue on latest stable version #131.0.6778.142 using macOS 14.6.3  by following steps from comment #1

Observed that, for 'allow this time' option after exit from full screen again permission pop up appear

Please find screencast attached below

Reporter@: Could you please review the screencast and let us know if anything is missed from our end.


Thanks..!!

The screecast showcases the issue, but it is not just from entering and exiting fullscreen, its anytime you call unlock and then lock again. If you play more of the web game, (try walking up to the notebook on the desk right of the computer.) and then when the UI opens it calls unlock and then when you click the exit button it will incorrectly make the permission pop up appear.

Thanks for looking into this!
