I was able to reproduce the failure on tip-of-tree and on r27971 using run-webkit-tests imported/w3c/web-platform-tests/html/semantics/links/links-created-by-a-and-area-elements/htmlanchorelement_noopener.html -1 -f -iterations 500 --exit-after-n-failures 2 --exit-after-n-crashes-or-timeouts 2

On r279969, the test failed, but I received a different diff:
