 Verifies that tapping the page during momentum scrolling does not dispatch click events to the page. To run the test manually, swipe up to scroll down; while the page is momentum scrolling, tap the screen to interrupt scrolling. The page should not observe any click events.
 
 On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
 
 
-PASS document.scrollingElement.scrollTop passed 1000
-PASS successfullyParsed is true

This is probably flaky for the same reason as fast/scrolling/ios/click-events-during-momentum-scroll-in-overflow-after-tap-on-body.html (i.e., we're not scrolling as we expected due to the simulated pan gesture).
