Some UI elements stay dark

STEPS TO REPRODUCE
1. Be using Breeze Light
2. Click the Brightness & Color widget
3. Click the dark mode toggle to switch to Breeze Dark
4. Click it again


OBSERVED RESULT
Some UI elements fail to fully change back to light. In this case, the button edges and slider.


EXPECTED RESULT
Everything fully changes back to light.


ADDITIONAL INFORMATION
Restarting plasmashell always fixes the colors.

Not 100% reproducible, sadly. Sometimes it's the switch handle that fails to switch, and sometimes, after restarting plasmashell a few times, it doesn't reproduce anymore.

Seems like a cache invalidation bug.
