--- Comment #3 from ayumi_kojima at apple.com ---
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:

--- /Volumes/Data/Builds/GoldenGate/test-282103/layout-test-results/imported/w3c/web-platform-tests/webrtc/RTCSctpTransport-events-expected.txt
+++ /Volumes/Data/Builds/GoldenGate/test-282103/layout-test-results/imported/w3c/web-platform-tests/webrtc/RTCSctpTransport-events-actual.txt

-PASS SctpTransport objects are created at appropriate times
-PASS SctpTransport reaches connected and closed state
+Harness Error (FAIL), message = Unhandled rejection: undefined is not an object (evaluating 'transport.state')

+FAIL SctpTransport objects are created at appropriate times assert_equals: expected (undefined) undefined but got (object) null
+FAIL SctpTransport reaches connected and closed state promise_test: Unhandled rejection with value: object "TypeError: undefined is not an object (evaluating 'transport.state')"

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