I am not able to reproduce the failure here but was able to reproduce a timeout using 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/IndexedDB/blob-valid-before-commit.any.html
