Created attachment 430550 [details]
a.html

Coming from a downstream bug report:
https://gitlab.gnome.org/GNOME/evolution/-/issues/1522

There are cases where form elements should be better drawn with the theme color, rather than "always light theme".

Michael also pointer to bug #197947 there.

Reproducer:

a) get the attached a.html
b) execute:

   GTK_THEME=Adwaita-dark /usr/libexec/webkit2gtk-4.0/MiniBrowser /tmp/a.html

the buttons (and the content) is in the light theme, even it would be better in the dark theme. At least the buttons.

I also tried to set content="dark" in the <meta>, but it didn't change anything (I thought it'll force the dark theme).

This is with webkit2gtk3-2.32.1-1.fc34.x86_64.

Basically in bug #197947 we made normal web content that doesn't know about dark mode work properly, and we made web content that uses only prefers-color-scheme work properly. But we don't support color-scheme at all. I think that's HAVE(OS_DARK_MODE_SUPPORT) which was disabled in bug #197947. We probably want to bring that back.
