[csswg-drafts] [selectors] [cssom] How should invalid selectors inside :is(), :where(), and :not() be treated for serialization? (#3676)

emilio has just created a new issue for https://github.com/w3c/csswg-drafts:

== [selectors] [cssom] How should invalid selectors inside :is(), :where(), and :not() be treated for serialization? ==
Split from #3264. It's not clear what happens if you add an invalid selector inside `:is` or `:not` or `:where` in terms of serialization.

 * Should we just skip them?
 * Should we serialize it as `:not(*|*)` (like invalid media queries which serialize as `not all`)?
 * Something else?
