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

run-webkit-tests imported/w3c/web-platform-tests/navigation-api/ordering-and-transition/transition-finished-mark-as-handled.html --ios-simulator

Referring to the history, it is shown that the tests were failing somewhere between 298426@main and 298454@main. Using reproduction steps above, I found that the tests were passing at 298444@main, but failed at 298445@main. At this time, I believe that the regression point is 298445@main.
