In High Contrast app icons shouldn't switch to symbolic
While it's true that white against black has the ultimate contrast, the decision to switch fullcolor icons to symbolic has a few negative implications:
- Apps identities usually lean onto colors, switching to white symbolic suddenly makes it harder to identify an app.
- Many 3rd party apps don't ship a symbolic icon making the experience feel unpolished/"under construction".
- Behavior is inconsistent with gtk/libadwaita.
I have a dejavu feeling about this, but couldn't find the original issue.
