This issue can be bisected to 254847@main using command:

run-webkit-tests --debug -f --clobber-old-results --exit-after-n-failures 1  --force  --child-processes=5 --iterations=500  --ipad-simulator  imported/w3c/web-platform-tests/streams/readable-byte-streams/construct-byob-request.any.worker.html

You may need to checkout commits to reproduce it passing before 254847@main.
