REPRODUCIBILITY:

I was able to reproduce this issue on the iOS 18.2 simulator at ToT using the following command:

run-webkit-tests --ios-simulator fast/forms/switch/click-animation-twice-fast.html --iterations 10

However, locally, this resulted in flaky image-only failures.

REGRESSION:

According to the dashboard, the regression range appears to be between 288854@main and 288876@main, however, the issue reproduces on a local environment when testing commits earlier than 288854@main.

I was able to reproduce this timeout, and track down a regression point. It repo's on iOS 18 Production tot running the test as follows:

run-webkit-tests --ios-simulator fast/forms/switch/click-animation-twice-fast.html --child-process=1

I was able to reproduce it as far back as 288873@main, but when I went to reproduce on the closest available build before that one (e.g. 288870@main) it no longer wasn't a constant timeout, or a timeout at all. Looking at the changes around that area, and given what this test is supposed to do, I'm fairly confident that: https://commits.webkit.org/288873@main is where this regressed, and broke this test.
