--- Comment #2 from Ben Schwartz <ben_schwartz at apple.com> ---
REPRODUCIBILITY:

I was able to reproduce these issues on macOS Ventura (13.5, 22G74/arm64) ToT using the following commands:

run-webkit-tests --debug --verbose imported/w3c/web-platform-tests/css/css-contain/content-visibility/content-visibility-video.html
run-webkit-tests --verbose imported/w3c/web-platform-tests/css/css-contain/content-visibility/content-visibility-video.html

REGRESSION:

I was able to identify a potential regression point at 268154 at main. As I don't have access to a reliable testing environment, I can't bisect to be sure; however, changes at this point seem directly related to the issue and the constant ImageOnlyFailures/crashes began at this point.
