REPRODUCTION:

I was able to reproduce this issue on macOS Ventura (13.5, 22G74/arm64) ToT using the following command:

run-webkit-tests --verbose --clobber-old-results --iterations 10000 --child-processes 10 -f --exit-after-n-failures 1 requestidlecallback/requestidlecallback-in-page-cache.html

REGRESSION:

I was able to identify a regression point at 266877@main, as this issue did not reproduce before then and changes at that point appear directly related to this issue.

NOTE:

This test is much more flaky in my local testing than on the bots.
