The test scrollingcoordinator/ios/sync-layer-positions-after-scroll.html is a flaky failure.

This looks like the test is outright failing. Tim, Simon, should this be investigated soon?
Test is still a flaky failure on iOS Simulator Release and Debug Verified locally with : run-webkit-tests scrollingcoordinator/ios/sync-layer-positions-after-scroll.html --ios-simulator --iter 100 -f --ios-simulator about a 40% failure rate. The diff is different than listed in this bug originally.
