Re: [csswg-drafts] [CSS Pseudo] Revisit CSS Custom Properties in highlight pseudos (#9909)

I made a demo to understand the current situation: https://codepen.io/leaverou/pen/poBzRVP

It looks like custom properties specified on `:root` *are* applied, but nothing below that, even if it contains the entire element. That’s …very unfortunate. With my author hat on, I was planning to base Prism v2 (one of the most popular syntax highlighters on the Web) on the CSS custom highlight API, and this would *severely* restrict what we can do, since different languages need different colors so these cannot just be defined on the root. In fact, I’m not even sure it's still possible.
