The following layout test is flaky on Mac WK2 Debug

http/tests/cookies/same-site/fetch-after-top-level-navigation-from-cross-origin-page.html

Probable cause:

Appears to be flaky timeout or missing failure as of 239333. 

Reproducible with: 

run-webkit-tests --root d239506 http/tests/cookies/same-site/fetch-after-top-level-navigation-from-cross-origin-page.html --iterations 500 -f --debug --exit-after-n-failures=1 --no-retry-failures

Did https://bugs.webkit.org/show_bug.cgi?id=193740 not fix this? It was working for me locally.

[Alexey Proskuryakov]

It did not, there's a crash with newer r240967: https://build.webkit.org/builders/Apple%20Mojave%20Debug%20WK2%20(Tests)/builds/1461
