Annotated screenshot of the Pager Icon bug.

SUMMARY
With the recent update of KDE Frameworks to 5.85, icons in the Pager grew larger than the borders of each workspace button. Currently my panel is 32px tall, on a 1366x768 Laptop display. There is a regression on the scaling of icons in the Pager alone; it doesn't seem to affect other widgets (System Tray,Icon-only Task Manager). I have attached an image with the bug.

STEPS TO REPRODUCE
1. Update KDE Frameworks to 5.85
2. Start Plasmashell
3. Observe bug.

OBSERVED RESULT
Icons in the Pager grew larger than the borders of each workspace button.

EXPECTED RESULT
Icons in Pager scale properly and remain within the borders of the displayed windows in the Pager.

ADDITIONAL INFORMATION
I use openSUSE 15.3 Argon, that's how I got the latest KDE packages. However, the bug can be reproduced in Tumbleweed according to this post: https://old.reddit.com/r/kde/comments/p82p2s/icons_inside_workspace_pager_is_bigger_than_each/

I have tried removing and adding the pager, as well as restarting the system (if logging out wasn't enough). No change.
