Marked test expectations https://trac.webkit.org/changeset/284555/webkit

I was able to reproduce the failure locally using run-webkit-tests --ios-simulator --iterations 50 --exit-after-n-failures 1 imported/w3c/web-platform-tests/html/cross-origin-opener-policy/reporting/navigation-reporting/report-only-four-reports.https.html -f

The test failed at r284510. No revision available to test for r284509, but I think the failure started at https://trac.webkit.org/changeset/284510/webkit.

r284510 is when I resync'd the test from upstream. I'll see what changes got merged for this particular test.

Looks like I was able to reproduce as well:
