Re: [csswg-drafts] [css-pseudo-4] Should Element.pseudo("unknown") be an error or return null? (#3603)

(In issue #3540 we marked non-before/after pseudo at-risk of being removed from the spec; if we do so, this function won't be useful as a detection mechanism anyway, and we need to decide what to do for `first-line` etc; should they really throw?)
