https://bugs.webkit.org/show_bug.cgi?id=48289 was raised for similar issue. If we remove this feature, both of these would be resolved.

As per discussion on https://bugs.webkit.org/show_bug.cgi?id=48288, we would not remove "darker" support. We can mark the bug as WONTFIX

Closing per discussion on bug 48288.

This decision was made 10 years ago in Bug 48288.
I wonder if the compatibility issue has changed 10 years later.
Given that both Firefox and Chrome do not support it.
