REPRODUCTION:
I was able to reproduce this on iOS 26.3 with the following:

run-webkit-tests --no-build --no-retry --no-show-results --exit-after-n-failures=1 --expect-pass --iterations=500 --force --ios-simulator --release compositing/iframes/overlapped-nested-iframes.html -f

I am going to mark expectations as pass fail while this pends investigation.</thetext>
