Vertical tabs hide animation results in favicons shifting rapidly

Description

When in minimized mode and un-hovering from the floating vertical tab strip, the favicons bounce a few pixels from side to side

I didn't dig much but I believe that's because sub components has a hard-coded insets based on the tab's width. IIRC, they don't interpolate the insets so the sub components could look like jumping back and forth.

Steps:

1. installed 1.58.89
2. launched Brave
3. enabled vertical tabs
4. loaded a few sites
5. clicked on the Expand tabs tab to collapse the panel
6. hovered over each of the site favicons

Confirmed there is no longer a "bounce" or "wiggle" effect when hovering over and out of minimized tabs

The new version of vertical tabs don't appear in fullscreen. So not tab at all in fullscreen

Hi, we'd removed vertical tab strip on fullscreen but decided to revert it as it's imperfect fix. Please refer to #33020
