This reproduces with ToT on a Release build as well: rwt --release --ios-simulator fast/visual-viewport/ios/min-scale-greater-than-one.html --iterations=100 --force --exit-after-n-failures=1

This is another case of subsequent taps in tests not working. The theory is that a double tap may be recognized, but the weird thing in this test is that the callback isn’t called, yet the click event comes through. This can easily be fixed by running the test with a 500ms timeout, which will prevent a double-tap from being recognized. But I think I’m going to finally dig into this to find a fix to the root cause since it affects testing and forces tests to run at slower rate than it should have.

This is actually a dupe of
https://bugs.webkit.org/show_bug.cgi?id=198610
, we need to restrict fast-click-everywhere to iPads only. *** This bug has been marked as a duplicate of
