Layout shifts as opacity mode changes

SUMMARY
The margins and paddings of Kickoff change strangely depending if the panel is in transparent or opaque mode.

The Transparent mode paddings look fine and are what the theme define but opaque ones look very much like default Breeze.

Please watch the short attached video for more accurate context. Title.

STEPS TO REPRODUCE
1. Pin Kickoff
2. Edit panel
3. Repeatedly switch between Transparent and Opaque so you can see the shift

OBSERVED RESULT
Kickoff margins and paddings change.

EXPECTED RESULT
Margins and paddings shouldn't change. They should respect the theme definitions, which Transparent mode seems to do.

The theme can have 2 separate backgrounds with different margins definitions for "opaque" and "transparent" cases, it might be a theme issue...

what is the theme used there?
