lwtheme-mozlightdark is removed

[black7375]

Describe the bug

:root[lwtheme-mozlightdark] was selector for default themes(system theme, a default light, and a default dark).

However, it was recently confirmed to be removed from Nightly.
It causes a lot of compatibility issues.

Expected behavior

It should be possible to distinguish whether it is the system default theme, compact light, compact dark or not.

Environment:

• Distribution
  • Original Lepton
  • Lepton's photon style
  • Lepton's proton style
• Firefox Version:
• OS:
  • Linux
  • Windows
  • Mac
  • Other:
• Theme:
  • Light
  • Dark
  • Alpenglow (System: Light)
  • Alpenglow (System: Dark)
  • System Default
    • GTK Theme Name (Linux only):
  • Other: (e.g. Photon Colors, Google Chrome Dark, Fairytale Of Nature)

It can be converted

:root[style*="--lwt-accent-color: rgb(240, 240, 244); --lwt-text-color: rgba(21, 20, 26);"], /* Light Theme */
:root[style*="--lwt-accent-color: rgb(28, 27, 34); --lwt-text-color: rgba(251, 251, 254);"] /* Dark Theme */

Is it related to this display problem of unfocused tabs in dark mode? (with auto system theme)

I'm on 95.0 (not Nightly), but the Gecko commit you referred to happened before it was released. Same problem on a fresh profile, but if I try it on 91.4.0ecr it works fine. Also on the normal dark theme (not system) it works fine.

If it's unrelated then I'll open a new issue.

Would you please make a new issue if it's not Nightly?

Done. #291
