Public bug reported: This bug happens with dark mode enabled, whenever I open Settings with Appearance pane open, or I enter Appearance pane from other panes in Settings. Whenever I do so, the app theme for legacy GTK3 applications (those not supporting the new GTK dark mode API) inadvertently changes to light mode. To turn back dark mode on for legacy apps, I have to use the toggle in Quick Settings, or click on any of the theme circles.
Normally, the dark mode theme for legacy apps should not change whenever Settings is opened with Appearance pane open, or Appearance pane is selected from other panes in Settings, just like GTK3 applications using the new dark mode API, and GTK4+libadwaita apps (which are not affected by this bug). A recording of the bug in action is attached along with this report.
