First of all I expect a self-view to simply take the local
mediaStreamTrack and display that, rather than loop it through the RTP
mixer.

If this occurs deliberately, to get it to work it will need to be
provided as a MST that the mixer offer the WebRTC endpoint, thus
originates deliberately under its own SSRC. See discussion of media
forwarding in Section 12.1.2.
