REPRODUCIBILITY:

I was able to reproduce this issue on macOS Ventura (13.5, 22G74/arm64) ToT using the following command:

run-webkit-tests -1 --clobber-old-results --verbose --iterations 100 --exit-after-n-failures 1 js/ShadowRealm-importValue.html

REGRESSION:

I was able to identify a potential regression point at 267947@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 first timeout instance is only a few commits later at 267955@main.
