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/screen-orientation/lock-basic.html --ipad-simulator --iterations=2

[Bryan Medina]

Referring to the history, it is shown that the tests were failing somewhere between 297539@main and 297557@main. Using reproduction steps above, I found that the tests were passing at 297542@main, but failed at 297543@main. At this time, I believe that the regression point is 297543@main.

For context, the test is a constant failure on iPadOS, but a flakey failure on iOS.
