This test seems to have been a flaky failure since this commit: https://commits.webkit.org/265309@main. It was introduced in this commit: https://commits.webkit.org/259019@main.

Furthermore, I was able to reproduce this test failure at macOS Ventura Production ToT running the test as follows:

run-webkit-tests http/wpt/service-workers/cache-mode-hard-reload-serviceworker.html --verbose --iterations 10
