title: Map is capturing Tap events from MapItemsControl elements
body: <p>I have a Bing <code>Map</code> control in my Windows Store app. I use the <code>Tapped</code> event of the map to place a Pushpin on the selected location.</p>
  
  <p>My map also contains a <code>MapItemsControl</code> with some clickable elements. Actually, they're some pushpins that show a popup when clicked.</p>
  
  <p>The problem is that when I click in any of these pushpins, the Map's Tapped event is also fired. </p>
  
  <p>I have also noticed that when this happens all the elements are rendered again, producing a strange behavior on the visual elements.</p>
  
  <p>Any idea why this is happening, and how can I avoid the Map capturing the Tapped event if the Tap has happend on other element?</p>
