Expected: video plays on left. about:webrtc RTCPeerConnection Statistics shows peer connection ends but no "Send: video/" or "Receive video/". This previously behaved as expected but the unexpected behavior was first observed in 44c4e62a38e1 Dec 14 on whereby.com, where it does not reproduce in a build --without-system-vpx. WebRTC Video can be received over the network by the --with-system-vpx build. When "Require H.264 video" is checked, then behavior is as expected.
