title: Semantic Zoom doesn't work in Windows 8 app
body: <p>I'm trying to use a SemanticZoom in my Windows 8 application and it seems to not work.</p>
  
  <p>Do I do something wrong here ?
  I tried pretty much everything I thought that could work but in vain : removed the rowdefinitions, removed the style, removed the templates but still not working...</p>
  
  <pre><code>&lt;Grid Style="{StaticResource LayoutRootStyle}"&gt;
      &lt;Grid.RowDefinitions&gt;
          &lt;RowDefinition Height="140"/&gt;
          &lt;RowDefinition Height="*"/&gt;
      &lt;/Grid.RowDefinitions&gt;
  
      &lt;SemanticZoom Grid.RowSpan="2"&gt;            
          &lt;SemanticZoom.ZoomedInView&gt;
               &lt;GridView x:Name="itemGridView"
