I was able to reproduce the text failure locally on my device running macOS Sequoia arm64 Debug ToT using the following command:

run-webkit-tests http/tests/xmlhttprequest/chunked-progress-event-expectedLength.html --iterations=500 -f

This is just a bad test, where parsing the HTML races with the test itself. It would be ideal to convert it to a js-test, but for a quick fix, moving test() into unload handler should suffice.
