[InitializedByEventConstructor] is no longer supported. You should use a dictionary, as in the specification. Also, as far as I know, we support required dictionary members already. Marking as Invalid, feel free to reopen if you find issues remain.

Ok, I modified the bug title to update RTCTrackEvent IDL as described in comment #0. Is it better to file a new bug?
