According to the history, it looks like the test started being flaky recently, but the test failed locally as old as with r283100. (Tried with r283274, r283270, r283260,and r283100)

Comment 5 ayumi_kojima 2021-10-12 15:25:02 PDT
With r283274 & r283270, the diff was slightly different with one from the test run.

I was able to reproduce the failure with the oldest revision available for BigSur (r268271) using run-webkit-tests --force --iterations 100 --exit-after-n-failures 1 http/tests/loading/preload-slow-loading.py -f
