This is very flaky, but I was able to reproduce the failure, thought not with much consistency. I reproduced it on iOS 17 Release ToT running the test as follows:

run-webkit-tests --ios-simulator --no-build --release fast/forms/ios/keydown-in-hidden-contenteditable-with-inputmode-none.html --iterations 1000 --child-process=1 --force

It's so flaky, and it appears to be very inconsistent in terms of a local repo. However, the history indicates that this test started to flake when we updated to iOS 17. Looking back in the history of iOS 16 testing, it does not appear to have been a flaky failure at all.
