You should probably pass the EventInit to the constructor so it can be passed to
Event's constructor.

Done.

This seems to be missing the various checks from the spec that can result in an
InvalidStateError, as well as setting the stop propagation flags.

[please use gerrit instead, 2016/05/03 21:38:33]

Now checking:
 - The event is being fired.
 - updateWith() is called only once.
Done.
