            Bug ID: 275685
           Summary: [GStreamer][WebRTC] Emit 'track' event upon applying
                    remote description
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebRTC
          Assignee: webkit-unassigned at lists.webkit.org

Currently, the GstWebRTC backend emits the 'track' event based on the 'pad-added' signal from webrtcbin.

However, the timing of this signal doesn't conform to https://w3c.github.io/webrtc-pc/#set-description, which mandates that the 'track' event should be emitted right after a remote description is successfully applied. Even before a 'connecting' connectionstatechange event.

Also, because of the above, there's some leftover code in PeerConnectionBackend to handle "pending track events" because of the GstWebRTC backend. We should be able to remove that.
