Looks like we've never flipped OS_DARK_MODE_SUPPORT for GTK.
Sort of the same as bug #208204. I agree that we need OS_DARK_MODE_SUPPORT.
I don't think it depends on that. `color-scheme` is about the native form elements; taking dark mode into account there is separate from having OS_DARK_MODE_SUPPORT.
Oh ok. The important context here is https://bugs.webkit.org/show_bug.cgi?id=197947 So with that in mind, yes - it does depend on that indeed.
Ok, it doesn't just depend on #208204, they are tied together and can't be fixed separately. Let's mark this one as a dup then. *** This bug has been marked as a duplicate of bug 208204 ***
