User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:100.0) Gecko/20100101 Firefox/100.0
Steps to reproduce:
- Open approximately 8 tabs (for a 1920x1080 16:9 screen). Maybe fewer tabs for a smaller screen, and more tabs for a larger screen.
- Click on "Add new tab" button
- Close the newly opened tab
Actual results:
The "Arrow down" button (search tabs) briefly appears and then disappears.
This also seems to cause the tabs to shift/move with a choppy animation.
(Recording of the issue: https://youtu.be/DCBlD8Rx8R0)
Tried narrowing the issue down with mozz-regression and as suspected, the issue is caused by the patch from #bug1759221
Expected results:
The "Arrow down" (search tabs) button should appear only when a specific number of tabs are opened (aprox. 20tabs on my screen specs). It should not appear briefly unnecessarily. The tab shifting/moving should be smooth, without any choppiness.

The bug has a release status flag that shows some version of Firefox is affected, thus it will be considered confirmed.

This prevents the overflow button and such from getting unexpectedly
shown mid-animation. With -moz-box-pack: start it doesn't look visibly
worse, afaict.

The patch landed in nightly and beta is affected.
:emilio, is this bug important enough to require an uplift?
If not please set status_beta
to wontfix
.

We'd need to uplift bug 1769512 so probably not.
