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.
This test appears to be consistently passing, let's remove the flaky expectation.
Ryan Haddad confirmed this is no longer happening as of 5/19/2022.
