This code won't be reached.  Your pointer events satisfy isMouseEvent too.  It
looks like WheelEvent overrides isMouseEvent to return it to 'false', you should
probably do the same for PointerEvent.

Done.

Any idea why we need this special case at all?  Presumably there's some reason
mouse (and so pointer) events need it.  But would be nice to understand why /
try to avoid the extra logic if possible (lots of complex events, eg. keyboard,
presumably go down the generic path below).

[mustaq, 2015/05/26 15:00:09]

It seems none of the 57 callers to dispatchEvent() pass mouse/touch events. So
the type-specific handling should be nuked IMO. I have started a thread with
hayato@ to double-check.
