Sequence of events:
1. Gnome Wayland becomes the default login selection for Intel+AMD users.
2. Ubuntu (deb+snap) and Fedora enable Firefox' wayland backend by default on Wayland. Firefox' wayland backend is tested in Fedora's CI.
3. After a long time, bug 1749174 enabled Firefox' Wayland backend at least in official Nightly, so that Wayland users are now testing Firefox' Wayland backend and no longer Firefox' X11 backend using Xwayland. X11 users are still testing Firefox' X11 backend.
4. Mozilla's CI currently tests the default configuration for outdated Gnome and Mesa versions.
