bug: Dark icons on dark theme

[ayaaop]

What happened?

I initially had light theme, but then logged out, switched to dark theme, then logged back in.

I'm using LibreWolf 128.0-2 on Windows 11 and was able to reproduce this on Chromium 126.0.6478.182 too

i cant access the new app right now so idk if this is still relevant. i'll just mark it as "needs reproduction"

to be clear, does this only happen when you do the following?:

1. log in with light theme
2. log out
3. log in again with dark theme

or can it also occur if you log in with dark theme to start with?
