Created attachment 320800 [details] HTML example file Steps to reproduce: 1) Open the attachment in iOS Safari on iPad 2) Scroll the scrollable div a few times using scroll gestures (swipe up/down). 3) Zoom page in to any level greater than default view. 4) Perform scroll gesture on the scrollable div. Expected result: Scrollable div should scroll each time a proper scroll gesture is performed. (Same behavior as default view of the scrollable div) Actual result: Scrollable div will scroll sometimes, other times the page will be panned or scrolled. Notes: See CSS in simple html page attachment for scrolling setup. Also, see attached movie as well for demonstration of behavior.
