Video of bug

SUMMARY
I noticed this during regular use with VSCodium, I initially thought this was from two instances of the same app existing in different activities but turns out this happens even without a second instance.

STEPS TO REPRODUCE
1. Start an app (tested this with VSCodium and Kate)
2. Move window below taskbar, this still works
3. Wiggle it a little bit, the graphical session now locks up

OBSERVED RESULT
The session locks up.

EXPECTED RESULT
The session doesn't lock up.

ADDITIONAL INFORMATION
Sorry for filing this under general, I don't know if this would be kwin or plasmashell and journal logs doesn't have any further info on who failed.

For brevity, here is the output of `qdbus6 org.kde.KWin /KWin supportInformation` as well: https://invent.kde.org/-/snippets/3365
