Re: [csswg-drafts] [CSS-PSEUDO][CSS-UI] Detection of base HTML attribute implementation support (#6195)

Right. To be able to style things properly, we need to detect the combination of:
* base styling is supported for this type of element
* base styling is set on this particular element

`@supports` might be extended to cover the first one, but it won't do the second one. Attribute selectors can be used to check on the second one, but not on the first one. Using the two in combination is clumsy, and error prone. So I think that a pseudo class is what we want.
