title: Grid in a Grid with RowDefinition Height="auto" suppresses Height="*" of child Grid's RowDefinitions
body: <p>I have the following code:</p>
  
  <pre><code>&lt;Grid&gt;
      &lt;Grid.RowDefinitions&gt;
          &lt;RowDefinition Height="Auto"/&gt;
          &lt;RowDefinition Height="*"/&gt;
          &lt;/Grid.RowDefinitions&gt;
      &lt;Grid Grid.Row="0" TextBlock.Foreground="Blue" ShowGridLines="True"&gt;
          &lt;Grid.RowDefinitions&gt;
              &lt;RowDefinition Height="*"/&gt;
              &lt;RowDefinition Height="*"/&gt;
              &lt;RowDefinition Height="*"/&gt;
          &lt;/Grid.RowDefinitions&gt;
          &lt;TextBlock Text="test" Grid.Row="0" /&gt;
          &lt;TextBlock Text="test" Grid.Row="2" /&gt;
      &lt;/Grid&gt;
  
      &lt;Grid Grid.Row="1" TextBlock.Foreground="Red" ShowGridLines="True"&gt;
          &lt;Grid.RowDefinitions&gt;
              &lt;RowDefinition Height="*"/&gt;
              &lt;RowDefinition Height="*"/&gt;
              &lt;RowDefinition Height="*"/&gt;
          &lt;/Grid.RowDefinitions&gt;
          &lt;TextBlock Text="test" Grid.Row="0"/&gt;
          &lt;TextBlock Text="test" Grid.Row="2"/&gt;
      &lt;/Grid&gt;
  &lt;/Grid&gt;
  </code></pre>
  
  <p>It's simply two equal grids with three rows, all three which should be of equal size (each in its own grid, that is). </p>
  
  <p>The bottom grid, contained in the parent row with a height of "*" behaves as expected. Each row is of equal size, regardless of what is put into it. </p>
  
  <p>But the top grid, contained in a row with height Auto, seems to discard the Height="*", and behave as if they had Height="Auto". The first and third row gets exactly the height they ask for, and the second, the empty row, is just given a height of 0. Is this normal behaviour? And if so, why is it the way it is?</p>
  
  <p>This is how it appears:

  <p>And this is how I would expect it to work:
