I was able to reproduce the time outs locally on my device running iOS 18 Simulator Release ToT using the following command:

run-webkit-tests <test_name_here>  --ios-simulator

It looks like it regressed somewhere between 298843@main and 298854@main....although I am not able to pin point the exact regression point.
