STEPS TO REPRODUCE:
I was able to reproduce this failure at macOS Tahoe ToT running the test as follows: 

run-webkit-tests fast/animation/request-animation-frame-throttle-subframe-zero-size.html --iterations 2000

I am going to mark expectations for this test as a pass failure while it is under investigation.
