This test began flaking recently. I am able to reproduce the error with command:
run-webkit-tests --iterations 2000 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --debug-rwt-logging --no-retry --force --no-build -f imported/w3c/web-platform-tests/streams/transform-streams/terminate.any.html
