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 imported/w3c/web-platform-tests/css/css-scroll-anchoring/shadow-dom-subscroller.html --ios-simulator --iterations=5

I was able to find the regression range/point by testing at 299281@main using the reproduction steps mentioned above, where it passed, and started to fail at 299283@main. As of this point, I believe the regression point is somewhere between 299282@main and 299283@main
Alexey Proskuryakov
This would make it 299282@main, as 299283 is clearly unrelated. A bit surprising, but that could just indicate a significant bug.
