Bug 1526801 [wpt PR 15292] - [PeerConnection] Fire signalingstatechange event at the right time, a=testonly Automatic update from web-platform-tests [PeerConnection] Fire signalingstatechange event at the right time Prior to this CL, the event was fired before the transceiver state was updated, in contradiction with the spec, which says it should be fired after the transceiver state is updated.
