The attached test failures were seen while running run-webkit-tests on the ios-sim-ews.

I highly doubt that simulator failed test is my patch. It's not obvious where in the test it would call the object constructor. All the test does is add some event listeners. Also, looking at the history for the test it looks like it was failing before, assuming the simulator is running WK1 and not WK2. http://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=fast%2Fscrolling%2Fios%2FscrollTo-at-page-load.html
Right, there are some scrolling tests that rarely if ever fail on regular bots, but are super flaky on EWS, up to becoming false positives. This is non-trivial, because they have to fail twice with a patch, and then to pass without the patch.
Bug 159086 has an even more obvious example of this.
> assuming the simulator is running WK1 and not WK2
No, iOS EWS runs WK2. iOS WK1 tests are not maintained at this time.
