Steps to reproduce:
Enable built-in Dark theme, check pages, install and enable Dark Space theme (https://addons.mozilla.org/firefox/addon/nicothin-space/), check pages, use about:debugging to test a modification to Dark Space theme, check pages
With the default "Website appearance" setting of "Firefox theme" or "Nightly theme", the results are not as expected:
Built-in dark theme: about:home, about:addons, about:config, about:debugging, and about:preferences all have a dark background; Github (https://github.com/mozilla/) has a dark background
Unmodified Dark Space theme: only about:home has a dark background
Dark Space theme with
"color_scheme": "dark" added to the theme / properties key in manifest.json: same desirable results as built-in Dark theme
Firefox should continue to auto-detect which add-on themes are dark themes (i.e., add-on authors should not be required to explicitly add the color_scheme property).
For reasons I can't understand, Mozregression yielded:

Perhaps that's not the correct commit??
