Drive-by comment: seems that in Firefox 78+, and the upcoming Safari 14 (currently in the Technology Preview stage), the `:is()` and `:where()` pseudo-classes become invalid when an invalid selector is included in the list. For example, `document.querySelectorAll('div:is(div, :bogus)')` throws in both.
