I was able to reproduce a failure 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 -1 imported/w3c/web-platform-tests/service-workers/service-worker/clients-matchall-order.https.html
