title: getIntersectedShapes in safari ipad
body: <p>I have the latest kineticjs(4.3.1) and i use hammerjs for touch events initiated within the kineticjs wrapper (div element).
  I need to call getIntersectedShapes on the 'onDrag' event. After doing that and checking the drag event on an ipad i only get the dragstart event(i can't debug so i don't know if i got an error).
  Doing the same action on a desktop(safari + chrome) or on iPad chrome works like a charm. only safari on iPad is a problem.
  I use latest browser versions both on iPad and desktop.</p>
  
  <p>Hope you can help...
  thnx</p>
