Description:
transitions/flex-transitions.html
Is a flaky failure on macOS ToT. The test expectation was removed in 273266@main. The test was constantly failing before and after the commit it's still failing but with less frequency.
This issue can be reproduced by using the command:
run-webkit-tests --root --exit-after-n-failures 1 --debug <test>

I can't reproduce the flakiness locally with 100 iterations in debug:
run-webkit-tests --debug --exit-after-n-failures 1 --iterations 100 --debug transitions/flex-transitions.html
Alexey Proskuryakov
Could be CPU load dependent, can you reproduce if you run multiple in parallel (--fully-parallel)?
