Cannot create offer after stop transceiver

[medved276]

I use peerConnection with some transceivers.
When I stop 2 of them...
pc.getTransceivers()[0].stop()
...I try to createOffer at some moment.
But I got
Failed to execute 'setLocalDescription' on 'RTCPeerConnection': Failed to set local offer sdp: The m= section with mid='2' should be rejected.
What incorrect?
