The first failure in the history goes back to r281553 (WPE 4.19.0 wk2 Release). I was able to reproduce the failure locally at TOT and r282326 using run-webkit-tests --debug --iterations 50 --exit-after-n-failures 1 imported/w3c/web-platform-tests/html/cross-origin-opener-policy/coop-navigated-history-popup.https.html

Marked test expectations: https://trac.webkit.org/changeset/282407/webkit

The test is failing on iOS Release as well. Updated test expectations: https://trac.webkit.org/changeset/282476/webkit
