1363815 - RTCPeerConnection: Attempting to view RTCPeerConnection.prototype contents in web console results in TypeError

Status: NEW

(Core :: WebRTC: Audio/Video, defect, P3)

Description

Attachment: rtcpeerconnection-typeerror.png

In Firefox Nightly's Web Console, I typed `RTCPeerConnection.prototype`, hit enter and then clicked on `34 more...` to expand the list. The list does not expand, instead a TypeError exception is thrown: 

`TypeError: 'get peerIdentity' called on an object that does not implement interface RTCPeerConnection.`

Clarification: the list of properties does show in the panel on the right. The bug is ONLY the TypeError

Mass change P2->P3 to align with new Mozilla triage process.

I'm seeing a very similar issue, the following error is printed to the console when the React DevTools extension attempts to display an RTCPeerConnection object in the sidebar.

TypeError: 'get localDescription' called on an object that does not implement interface RTCPeerConnection.

The backtrace isn't particularly useful:
