The following layout test is failing on iOS Simulator Release WK2
fast/visual-viewport/ios/min-scale-greater-than-one.html
Probable cause:
Test recently started showing up on the dashboard around r242531 as a flaky failure on iOS Sim Release. Is a very flaky failure on dashboard, when running test locally it fails 10 times in 60 iterations with 1 child process, unsure if it's because I'm running iterations, but I do get the same diff that is on the bots.
I tested with several revisions from when it was made until current, but there appears to be a lot of code changes so I do not get consistent results.
Reproduced with:
run-webkit-tests fast/visual-viewport/ios/min-scale-greater-than-one.html --iterations 500 --child-process 1 --ios-simulator --exit-after-n-failures=10 --no-retry

Dean, did fast tap break this?
Jon Lee
Can we combine this with 196236?

I was hesitant because the generally flakiness of the test is addressed here, while the consistency of the Debug failures were isolated to a different revision.
I can if it makes it easier for tracking however?
Ryan Haddad
I'm going to go ahead and dupe this since the diff is the same.

I have marked this test as failing while this is investigated further.
