Automatic update from web-platform-tests [Reference Target] Use relatedTarget for event propagation Replace the reference target handling in GetShadowRootParent with an approach that uses Event's existing relatedTarget concept, per discussion at [1]. The way this will work is that for CommandEvent, ToggleEvent, SubmitEvent, and InterestEvent, instead of an internal source/submitter, the events will use relatedTarget. The getters for these no longer need individual retargeting since relatedTarget gets retargeted as part of event dispatch. When relatedTarget is non-null for one of these event types, we'll dispatch it as a composed event. The result is that when the source/submitter is in a parent shadow because of reference target, we'll bubble the event into that shadow (but no further, due to the way relatedTarget already affects event dispatch).
