Are 3 almost constant text failures on iOS ToT. It appears that these tests share a similar (Harness Error (TIMEOUT), message = null) error which causes the 3 layout tests to fail frequently. They also appear to have the same regression point.

I'm unable to get these tests to fail/pass according to the history shown.

When running these tests with the --child-processes=X & -f parameter they always fail otherwise, they always pass. They also take a long time to run.

History would indicate that the regression should be around 252960@main.

Commands run:

run-webkit-tests --ios-simulator --child-processes=4 -f imported/w3c/web-platform-tests/html/cross-origin-opener-policy/tentative/restrict-properties/iframe-popup.https.html

run-webkit-tests --ios-simulator imported/w3c/web-platform-tests/html/cross-origin-opener-policy/tentative/restrict-properties/iframe-popup.https.html

run-webkit-tests --ios-simulator --debug --child-processes=4 -f imported/w3c/web-platform-tests/html/cross-origin-opener-policy/tentative/restrict-properties/iframe-popup.https.html

run-webkit-tests --ios-simulator --debug imported/w3c/web-platform-tests/html/cross-origin-opener-policy/tentative/restrict-properties/iframe-popup.https.html

I also downloaded builds similar to the bots and ran the same commands.
