I was not able to reproduce the crash locally on BigSur (intel) using run-webkit-tests -1 --force --debug --iterations 500 --exit-after-n-crashes-or-timeouts 1 fast/selectors/pseudo-element-inside-any.html According to the history, the flaky crash appears to have started recently at around r284314.
