[Bryan Medina]

I was able to reproduce the text failure locally on my device running macOS Sequoia Release ToT using the following command:

run-webkit-tests <test_name_here>

[Bryan Medina]

Referring to the history, it is shown that the tests were failing somewhere between 298118@main and 2981121@main. Using reproduction steps above, I found that the tests were passing at 298120@main, but failed at 298121@main. At this time, I believe that the regression point is 298121@main.

[Bryan Medina]

It seems that this test has now regressed for all configurations of iOS, also at 298121@main.

Expectations will be set.
