Authors would definitely benefit from knowing that selectors within :is() and :where() are invalid, allowing them to correct those errors. Therefore I've created https://bugzilla.mozilla.org/show_bug.cgi?id=1664739 and https://bugzilla.mozilla.org/show_bug.cgi?id=1664740 for two ways how to expose this info to them.
