I don't have access to an Apple Silicon Mac, so I can't reproduce in that environment. However, I was able to reproduce the failure on an Intel Mac running Catalina Debug ToT using the following test:
run-webkit-tests fast/scrolling/mac/overflow-scrollbars-toggle-dark-mode.html --iterations 1000 -f
I was also able to reproduce the failure over 5,600 revisions back. So this appears to have been a flaky failure for a while.
Updated test expectations here to flaky ( Pass ImageOnlyFailure ) here:
