According to the history, it appears that the flaky failure has started somewhere between r282358 and r282379.

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
