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
