title: Content Alignment in Xamarin Forms does not work?
body: <p>i have a simple custom tile control in Xamarin Forms and i can't get the inner alignment to work like i would it expect in MS Xaml. (on Xamarin.iOS (for iPad!))</p>
  
  <pre><code>    &lt;ContentView.Content&gt;
  
      &lt;Grid x:Name="LayoutGrid" BindingContext="{x:Reference tile}" BackgroundColor="{Binding Color}"&gt;
          &lt;Grid.GestureRecognizers&gt;
              &lt;TapGestureRecognizer Tapped="ExecuteCommandOnTapped" /&gt;
          &lt;/Grid.GestureRecognizers&gt;
  
          &lt;StackLayout HorizontalOptions="Start" VerticalOptions="End" BackgroundColor="Aqua" Orientation="Vertical"&gt;
              &lt;Label x:Name="AdditionalDescription" Text="{Binding AdditionalText}"   TextColor="{x:Static local:AppColors.AppBackground}" VerticalOptions="End" HorizontalOptions="Start" XAlign="End" YAlign="End" Font="32" /&gt; 
              &lt;Label x:Name="Description"           Text="{Binding Text}"             TextColor="{x:Static local:AppColors.AppBackground}" VerticalOptions="End" HorizontalOptions="Start" XAlign="End" YAlign="End" Font="Bold, 32" /&gt;   
          &lt;/StackLayout&gt;
      &lt;/Grid&gt; 
  
  &lt;/ContentView.Content&gt;
  </code></pre>
  
  <p>Is there any trick to align the Inner Stacklayout to the bottom?
  When i use the control, the control has the expected size (fills the entire available space) but the inner stack layout is aligned to top. :(</p>
