title: Large white space appearing between Text and Line of Picker after adding inside <AbsoluteLayout>
body: <p>Adding below Picker inside StackLayout works fine.</p>
  
  <pre><code>&lt;Picker HorizontalOptions="FillAndExpand" Title="Select Category" 
                                      x:Name="categorypicker" ItemDisplayBinding="{Binding Title}" /&gt;
  </code></pre>
  
  <p>Now, I need to add loaders on the right side of these pickers,so encapsulated <code>&lt;Picker&gt;</code> and <code>&lt;ActivityIndicator&gt;</code> inside an <code>&lt;AbsoluteLayout&gt;</code> like this:</p>
  
  <pre><code>&lt;AbsoluteLayout AbsoluteLayout.LayoutBounds="0,0,1,1" AbsoluteLayout.LayoutFlags="All"&gt;
                                  &lt;Picker AbsoluteLayout.LayoutBounds="0,0,1,1" AbsoluteLayout.LayoutFlags="All" HorizontalOptions="FillAndExpand"   Title="Select Category" 
                                      x:Name="categorypicker" ItemDisplayBinding="{Binding Title}" /&gt;
                                  &lt;ActivityIndicator AbsoluteLayout.LayoutBounds="1,0,40,1" Scale="0.6"
                                                     AbsoluteLayout.LayoutFlags="PositionProportional,HeightProportional"
                                                     IsRunning="{Binding ShowCategoryLoader}" /&gt;
                          &lt;/AbsoluteLayout&gt;
  </code></pre>
  
  <p>Everything else seems to be working fine, but now a large space is showing between text and line in picker.
  Tried with HeightRequest in Picker, ActivityIndicator &amp; AbsoluteLayout.But nothing seems to work.</p>

  <p><strong>Note:</strong> It would be great ,if it can be fixed with only XAML and not programmatically code behind or custom picker</p>
