It looks like the regression range is somewhere from 299180@main and 299182

I was not 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> --iterations=1000 --child-processes=1

[Jonathan Bedard]

We have a regression point here, either https://commits.webkit.org/299181@main or https://commits.webkit.org/299182@main. https://commits.webkit.org/299181@main seems more likely, although quite surprising.
