[Bug 21066] Provide an event path API

https://www.w3.org/Bugs/Public/show_bug.cgi?id=21066

--- Comment #49 from Hayato Ito <hayato@chromium.org> ---
Thank you. I am triaging issues in the Shadow DOM spec.

I think this issue can be actionable and can be fixed.

Of course, as we know, in Blink, a Window object has been receiving events so
far. The current Shadow DOM spec and the implementation differs. I'd like to
fix this. The blink's implementation won't change.

However, event.path will become to includes Window object at the beginning of
that as a result. This is the only user visible change, I think.

We might have a plan B:
   event.path API return EventTarget[] where Window object is removed from the
event path.

If someone have a strong concern about the compatibility and prefer plan B,
please let me know that.
