Hi, assuming peer-A creates an offer with a single audio track and
receives a proper SDP answer from peer-B, can peer-B much later send a
completely different SDP ***offer*** so peer-A calls
setRemoteDescription("offer", new_sdp) ?

>From my tests this just works (in Chrome) in case the SDP is "similar"
to what it was negotiated before, but terribly fails if the new SDP
offer has new streams or whatever. In fact, it mostly fails when
calling setLocalDescription() after createAnswer().
