I was able to reproduce the failure at TOT using run-webkit-tests --force --iterations 50 --exit-after-n-failures 1 imported/w3c/web-platform-tests/webrtc/RTCSctpTransport-events.html
With older revisions (r282000-r282103) though, the test failed but with a different diff:

The test failed at the oldest revision available (r281695) with the same diff above.

It appears that it started at https://trac.webkit.org/changeset/282341/webkit
I was able to reproduce the failure at r282341 and newer revision and the test passed at r282340:

Weird thing is that r282059 failed with the same diff above on the testing machine, but I could not reproduce the same failure locally.

Seems unlikely that the cssom-view tests would cause an unrelated test to fail.
