Re: [csswg-drafts] Add a property to the `CSSPseudoElement` IDL interface to determine if a pseudo element "exists" (#12158)

one thing to be careful of with this kind of API is that it might force a style/layout computation, depending on when it is called, as pseudo-elements are created by the style and layout system.
