no html variant?  maybe a bug should be filed

[Jacob, 2012/04/26 19:32:45]

there is one but is a bit ugly for this edge case
document.on[event.type].dispatch(event)

Done.

     } catch (EventException e) {
       Expect.equals(EventException.UNSPECIFIED_EVENT_TYPE_ERR, e.code);
       Expect.equals('UNSPECIFIED_EVENT_TYPE_ERR', e.name);
