Steps to reproduce
- Run notifications from master
- Have a background that will have icons black, also dark mode
- Look at the notification bell
Expected behaviour
The bell is black
Actual behaviour
It is an old, white bell

This also happened after increasing the cachebuster, and also when switiching to light mode (all icons are black, but the bell)
I have not seen a similar bug report so far. Apologies if I oversaw one.
