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/css/css-contain/content-visibility/content-visibility-size-containment-001.html --ios-simulator

The regression point seems to be somewhere between 298688@main and 298709@main...

I am unable to find a direct/exact regression point at this moment.
Perhaps it is due to changes at 297800@main...

[Bryan Medina]

Modified expectation as the failure is now happening on both configurations of iOS, not just Debug.
