Re: [csswg-drafts] [css-scroll-snap-2] Should pseudo-elements show up as null SnapEvent.snapTargetBlock/Inline (#10175)

I think that if a pseudoElement is targeted by a snap event, we should handle this similar to a pseudoElement targeted by other targeted events (e.g. pointerevents / ui-events) where the target is the owning element of the pseudoElement, e.g. try clicking on the `::before` or `::marker` objects in https://codepen.io/flackr/pen/NWmyRra

If in the future developers need to know which pseudo-element was the target we could follow the precedent of [animation events](https://drafts.csswg.org/css-animations/#interface-animationevent-idl) and add a string pseudoElement representing the targeted pseudo element but I think we probably don't need to add this yet as we don't have this for most events.

More generally I think we do want to be able to target pseudo elements, and there is an [interface for them to be event targets defined in pseudo-4](https://www.w3.org/TR/css-pseudo-4/#CSSPseudoElement-interface), but this will be a backwards incompatible change for other targeted events.
