[Bug] Active selection text color remains dark

[Luv0103]

Describe the bug
In my main vault, the text color of selected items (in the file explorer, settings sidebar, etc.) remains dark instead of switching to white, making it hard to read on a dark background. This issue is isolated to my main vault. The theme and Style Settings work correctly in a fresh vault.

To Reproduce

1. Open the main vault.
2. Select any item in the file list or settings menu.
3. Observe the dark text color on the dark background.

Expected behavior
The selected text should be white for contrast.

Additional context
V1.9.12
Exported and imported all Style Settings to a new vault → works fine.
Disabled all community plugins (except Style Settings) → issue persists.
Disabled all CSS snippets → issue persists.
