What did you expect?
PeerConnectionState to transition to "failed" when DTLSTransport state goes to "failed"
What happened?
No state change in PeerConnection. (PeerConnection state in the test eventually goes to "closed" along with ICE connection state.
According to the W3C WebRTC spec, when a DTLSTransport is in "failed" state, the PeerConnection should also transition to "failed" state:
failed: Any of the RTCIceTransports or RTCDtlsTransports are in a "failed" state.
Currently, the PeerConnection state does not reflect the DTLS failure (it goes directly from connecting to closed).
