[Bug] Sidebar doesn't adapt to dark version of theme

[aaronliu0130]

Abstract

I use a theme, Alpenglow (aka. Firefox Radiance), which has a different background image under dark mode using the undocumented object "dark_theme" in its manifest.json. TST still uses the light mode background image under dark mode for its background.

Steps to reproduce

1. Start Firefox with clean profile.
2. Install TST.
3. Install Alpenglow or any theme with a different dark mode background image as specified in the abstract.
4. Under "Dynamic Themes" of about:prefs, click "Force Dark Mode".

Expected result

The TST sidebar uses the background for dark mode, which, in Alpenglow's case, is purple.

Actual result

Environment

• Platform (OS): Win11
• Version of Firefox: 115.8.0
• Version (or revision) of Tree Style Tab: 3.9.22

Actually, I don't think any dark mode style is respected except for the color of the selected tab, maybe. TST's tab text doesn't change in dark mode either.
