I was able to reproduce the failure at iOS-15 Debug ToT using the following test:


run-api-tests <test goes here> 


I was also able to verify a regression point. The failure was reproducible back to r293671, and it was not reproducible at r293670. So it appears that https://commits.webkit.org/250173@main introduced this failure.
