Why not fix pseudoElementNameForEvents to handle all pseudo elements?

Yeah, I think this should stay on PseudoElement. If you were going to update the list, it's where you would look. Not inside WebAnimationUtilities.

Actually, we want to move away from PseudoElement which are only ever created for ::before and ::after pseudo-elements. We've moved to using the Styleable struct throughout the animation code so that we rely on PseudoElement as little as possible.

We only ever need to convert from a PseudoId to a String for animations, so I believe this is the right place.
