I've been able to repro locally using the following command run-webkit-tests --no-retry imported/w3c/web-platform-tests/2dcontext/imagebitmap/createImageBitmap-drawImage.html --iterations=1000 -f -g
Test marked as flaky in: https://trac.webkit.org/changeset/236065/webkit
<rdar://problem/44523117>
re-opening, because test was only marked as flaky, issue has not been resolved.
