Specification: https://dom.spec.whatwg.org/#concept-event-dispatch This also introduces shadow roots due to it being a requirement of the event dispatcher. However, it does not introduce the full shadow DOM, that can be left for future work. This changes some event dispatches which require certain attributes to be initialised to a value.
