Description

[Jan-Ivar Bruaroey [:jib] (needinfo? me)]

+++ This bug was initially created as a clone of Bug #1264479 +++

The spec now has these attributes on RTCPeerConnection to allow ICE renegotiation while retaining the current connection.

From my reading of the spec, in "have-remote-offer" of a subsequent renegotiation, this means the two should report different values:

  currentDescription = what was negotiated last we were in "stable" state.
  pendingDescription = what's in the processs of being negotiated, or null.

Instead, I'm seeing both report the latter.

STRs:
 1. Open https://jsfiddle.net/jib1/Ljp1x8h5/ and share camera.

Expected result:
  answer
  have-remote-offer
  answer
  offer
  true

Actual result:
  answer
  have-remote-offer
  offer
  offer
  false

This is causing https://searchfox.org/mozilla-central/source/testing/web-platform/tests/webrtc/RTCPeerConnection-setRemoteDescription.html to fail.
