REPRODUCTION:
I was able to reproduce this failure on macOS Tahoe ToT arm64 with the following:

run-webkit-tests --force --release --no-retry --iterations 1000 fast/events/onunload-not-on-body.html

I am going to mark expectations as pass fail while this pends investigation.

Looks like the test is flaky because it relies on an auto-generated frame identifier (frame3 or frame4) & this is causing the frame number to vary between runs. I’m going to push a patch that resolves this, please review (assuming this is NOT a webkit issue).
