We fail to throw the NOT_SUPPORTED_ERR error when calling document.createEvent('TrackEvent'). I believe this is a broader WebCore issue that we don't follow the latest DOM spec that this method should only be used for legacy events. See http://dom.spec.whatwg.org/#dom-document-createevent. 776803 1 webkit-bug-importer 2012-11-27 08:45:02 -0800 <rdar://problem/12758230> 777028 2 abarth 2012-11-27 11:32:13 -0800 http://dom.spec.whatwg.org/#dom-document-createevent says that we should be able to create any sort of supported event via this API. 777064 3 ian 2012-11-27 11:58:56 -0800 Adam, I think you're misreading the algorithm. (Though I don't really understand why it's specced that way.) 777126 4 abarth 2012-11-27 12:40:25 -0800 Ah, yes. Thanks. That's quite different from the behavior we have currently. 1168153 5 webkit 2016-02-25 11:26:31 -0800 Still not spec compliant.
