What would help me is to better understand the requirements of the
shadow DOM with respect to event dispatch. To calculate the dispatch
tree, you're using the event type, right? Then at certain points
you're also making modifications to the Event object being dispatched,
correct? Is there anything else? I'd like to expose those as hooks
from the dispatch algorithm, but I'd like to make sure I'm not missing
