Details

Once bug 1664718 is implemented, it is valuable to know for authors when a selector within :is() or :where() is invalid, allowing them to correct the mistake.

Therefore, a warning should be logged to the Console for the invalid parts within the selector.
If multiple selectors within those pseudo-classes are invalid, it is probably better to log individual warnings for each one, from a user perspective and, I guess, also from an implementor perspective.
