Tab Stash window does not retheme automatically when toggling light/dark mode

[derlade]

System Details

• OS Version: Linux 6.7.4-arch1-1
• Browser Version: Firefox 122.0.1
• Tab Stash Version: 3.0

Installed Browser Extensions:

• None that should interfere with Tab Stash according to the known incompatibility list

Describe the Bug

When the system theme (light/dark) is switched globally, Firefox recognizes this and also switches its theme automatically (if configured appropriately). Unfortunately, this does not apply to Tab Stash (or other tab management addons such as Sidebery), such that the previously enabled theme stays enabled. Closing and reopening the sidebar via Ctrl-Alt-S does not retheme the window, but weirdly enough opening Firefox sidebars such as bookmarks or history (or having them opened during global theme switch) forces Tab Stash to redraw and switch its theme.

Steps to Reproduce

1. Have Firefox and Tab Stash openend
2. Switch system theme globally (I do this with Night Theme Switcher in GNOME)
3. Observe that Tab Stash has not redrawn its window
4. Open bookmarks (Ctrl-B) or history (Ctrl-H) and switch back to Tab Stash
5. Observe that Tab Stash has now applied the current global theme

Expected Behavior

Tab Stash redraws its window immediately after global theme switch

Impact

Small usability issue

Some additional quirks: If Firefox is newly opened with either Tab Stash opened in the sidebar or without any sidebar, switching themes also redraws the sidebar window. As soon as the sidebar is changed to showing bookmarks or history, immediate theme switching is broken for the Tab Stash window.

Interesting! Unfortunately, this seems like a Firefox bug, and not something I can do much about in Tab Stash. Tab Stash only tells Firefox which colors to use in which mode, and Firefox decides when to apply them (there is no logic in Tab Stash for handling switching per se). So it seems likely Firefox is just not telling its sidebar when the switch happens, for some reason.

Thanks for letting me know though, I'll leave this open in case others run into it too and can shed more light on what's happening.
