Obtain a tab group pop-up (either when creating a new group or right clicking an existing one), preferably close to the window edge.
Scroll the tab list while the pop-up is open.

Expected results:

The pop-up should be closed once the associated tab group is scrolled out of view or stay at the edge within the browser window.

The Bugbug bot thinks this bug should belong to the 'Firefox::Tabbed Browser' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I am not able to reproduce the issue on Win11x64 using Firefox builds 138 and 140.
Beish97, can you please see if this also happen with a new and empty profile? See https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems#w_6-create-a-new-firefox-profile
Thank you.

Hi,

The video capture included was taken on a fresh profile. I can confirm that this also happens on my work machine, which is Windows 11 Pro x64 with Firefox 138.0.1 (also when using a fresh profile).
