Describe the issue

When changing the colours in the Manage / Appearance settings, the changes are no longer applied everywhere (see screenshots below). This is for both the light and dark theme.

This used to work in 5.13.2 and is broken since at least 5.14.3.

I already tried

• I've read and searched the documentation.
• I've searched for similar filed issues in this repository.

Steps to reproduce the behavior

1. Run Weblate 5.14.3
2. Go to Manage / Appearance
3. Change colors
4. Go back to the dashboard --> inconsistent colors

Expected behavior

The colours are changed everywhere.

Screenshots

Setting the colours:

The colours are partially gone in the dashboard:

But are back in some random pages (the project settings and backups pages for instance):
