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

run-webkit-tests imported/w3c/web-platform-tests/html/browsers/browsing-the-web/overlapping-navigations-and-traversals/cross-document-traversal-cross-document-traversal.html  --ipad-simulator

Using reproduction steps above, I found that the tests were passing at 297503@main, but failed at 297504@main. Referring to the history, it is shown that the tests were failing at 297504@main. At this time, I believe that the regression point is 297504@main.
