I was able to reproduce the text failure locally on my device running iOS 18 Simulator Release ToT using the following command:

run-webkit-tests http/tests/security/clipboard/copy-paste-html-cross-origin-iframe-across-origin.html --ipad-simulator --iterations=50

It looks like this test has been flaky since it was introduced. I cannot seem to pin point a regression range.
