Description

Stefan: I have not been able to reproduce this bug, but I have experienced a similar and perhaps related bug (also intermittent) that causes a group to remain collapsed despite attempts to expand it.

Thanks for creating the bug, Stefan.

Shortly after I made the video, it started working again, without me doing anything notable (save for clicking a few more times).

I'll keep an eye out and report.

Update: I just experienced this identical and in my case, short-lived, bug for the first time. Below is my tab bar: P represents pinned tabs, X is ungrouped tabs, and O represents a group.

PP XXXX OOOOOOOOOO XXX O

The group on the far right of the bar, with a single tab inside, is the one that would not collapse despite clicking on it a few times. I believe I next closed an ungrouped tab (TBH, I was not tracking what I was doing) and then the stuck group collapsed the next time I clicked it, and now it expands/collapses as usual.

Thanks @shtrom.

Attachment: This is how Stefan's tab bar was set up when the right-most group, "TG Misc", stopped collapsing briefly
