List of popular contrib modules that need to be updated to support Admin theme's dark mode

Problem/Motivation

When Admin goes stable in Drupal 12 (🤞), I'd like contrib to be ready to support that. Any contrib module that implements CSS within their admin UI will likely need to be updated to use the new CSS variables.

I'm keeping a list here, so when the CSS is a bit farther along, I can open issues / MRs to help the contrib maintainers along.

List of contrib modules

• Diff - Split diff is all messed up in dark mode. Dropbuttons in header not horizontally aligned
• Webform - needs testing
• Field Group - Needs testing
