> When we try to move tabs with the Vertical Sidebar the Tabs are no longer displayed underneath the actual mouse cursor and I think it happens because of the extra +nr of tabs from the collapsed groups, I also noticed that not all of them will show that number, it usually enables if we collapse a group with an active tab in it. Please take a look at the video.

I just filed bug 1975486 to address this. The overflow counter should not display at all if the group doesn't contain the active tab, but there was some churn in the CSS during review so it must have slipped through.

I just filed bug 1975486 to address this. The overflow counter should not display at all if the group doesn't contain the active tab, but there is a bug that occurs when switching between horizontal and vertical tabs mode.
