title: Manipulation events in a ListBox in wpf4 is never raised
body: <p>I have a ListBox control defined within MainWindow and its IsManipulationEnabled property is set to true. I have the manipulation events (OnManipulationStarting, OnManipulationInertiaStarting and OnManipulationDelta) defined in the MainWindow. The goal here is to achieve a translation on the Listbox control, more like a flip functionality.</p>
  
  <p>However, these events are never raised. I am assuming that the selection events are in turn gobbling these events. When I use itemscontrol instead, it works fine. But the problem in using itemscontrol is that I do not get a selection state. Another option would be to work on raw touch, but manipulations are way easier.</p>
  
  <p>Why do the Manipulation events not fire on Listbox?</p>
  
  <p>Thanks in advance! </p>
