(Core :: WebRTC: Networking, defect, P3)

Description

[Michael Froman [:mjf]]

Specifically, this is seen in the test-verify version of RTCDtlsTransport-state.html on macOS seen here:
https://treeherder.mozilla.org/#/jobs?repo=try&selectedTaskRun=B1pqNTmtQ3eTGcQNftJ0MQ.0&revision=a5736998f2494aafc4aa3531bd991fe16742e7f5

In all the cases where the [DTLS transport goes to connected state] test times out, this messages always appears in the logs:
