should take eventPath.size() out of the loop

should we follow the Element->parentNode() hierarchy here instead of ax object hierarchy?

This is specified in the previous spec, and I think this would keep the same:
Accessibility input events go through capture and bubble phases, just like DOM events. The only difference is that the capture and bubble phases happen entirely in the accessibility tree.

Need a URL for the spec.

I don't think we want to duplicate all this code here.
We should templatize the one in EventDispatcher.cpp and re-use it for regular DOM events and accessibility tree instead.
r- due to this code duplication.

Where this event path specified?
Are we sure we want to use the accessibility tree to dispatch events?

Use auto.

The definition of the event dispatching isn't detailed enough in the current spec...
