According to manual, RTCPeerConnection has a property connectionState (Indicates the current state
of the peer connection by returning one of the strings).
Link to the manual = https://developer.mozilla.org/en-US/docs/Web/API/RTCPeerConnection
But my program (javascript) does not see it.
Developer tools (console in Firefox) do not show this property too – see curPeerConnection variable in the screenshot.
Why I do not see it ?
