imported/w3c/web-platform-tests/fetch/api/policies/referrer-origin-worker.html is a flaky failure and crash according to the flakiness dashboard.

The crash occurs on Sierra Debug WK1, this is a previously documented bug (link in see also).

The Flaky failures are on macOS Release Wk1 and on Sierra Debug WK1.

I was able to reproduce the failure on Sierra Release WK1 with:
run-webkit-tests imported/w3c/web-platform-tests/fetch/nosniff/importscripts.html -1 --iterations=100 -f --no-retry-failure

The test is flaky and will not fail every time the test is run. I had to run it 2-3 times to fail.
