SUMMARY
***
Tabs are 'jittery' on xfce4-terminal, mate-terminal, thunar and many other gtk3 apps. To recreate, open multiple tabs, then switch between them using Control+PageUp/Control+PageDown. The tabs will change in horizontal size slightly sometimes when toggling between them.

The problem is with lines 2787-2790 in gtk-3.0/gtk.css, which are currently used to address the following issue:
https://invent.kde.org/plasma/breeze-gtk/-/merge_requests/49#note_422893

Removing these lines breaks that issue, but fixes this one.
***


STEPS TO REPRODUCE
1.  Using xfce4-terminal, mate-terminal, thunar, mousepad, or other, open mutiple tabs
2. Switch between them using Control+PageUp/Control+PageDown

OBSERVED RESULT
The tabs will change in horizontal size slightly sometimes when toggling between them.

EXPECTED RESULT
The tab width should remain static.
