I think this will be fixed by <https://webkit.org/b/208603>.

If fixed by that patch let’s dupe.

I was unable to reproduce this before r258550 (bug 208603), but I am confident that it definitely shouldn't happen after. *** This bug has been marked as a duplicate of bug 208603 ***

This was fixed in r258550 and then broken again in r258623 (Bug 209200 - Web Inspector: the width of `WI.TabBarItem` can change if the detached window is resized).

# STEPS TO REPRODUCE: 1. inspect any page 2. undock Web Inspector 3. select the last tab in the tab bar 4. slowly make the Web Inspector undocked window horizontally smaller => once there is not enough room for all of the enabled tabs in the available space of the tab bar, the tab bar items will `flex-wrap`, which will cause the tab bar items at the end to be incorrectly perceived as very wide as they attempt to grow to fill any available space, which is huge due to `flex-wrap` and the fact that we choose to hide things starting from the right and moving left This should be resolved by bug 208603 (attachment 394129 [details]).
