EventInit should have default values for bubbles and cancelable
Last modified: 2013-02-22 12:31:59 UTC
bubbles and cancelable are false by default when event is created, and
it would make the spec easier to understand if that was the
case in the dictionary too.
Also, in Gecko it simplifies the implementation if we have
I don't see the point given document.createEvent(). Maybe for events that cannot be instantiated via that method?
