title: ScrollViewer steals focus
body: <p>Why in the next XAML clicking on disabled button cause ScrollViewer to steal focus from TextBox? Is it right? What is the workaround?</p>
  
  <pre><code>&lt;Window
  x:Class="WpfApplication1.MainWindow"
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  Title="MainWindow" Height="350" Width="525"
  FocusManager.FocusedElement="{Binding ElementName=TextBox}"&gt;
  &lt;ScrollViewer&gt;
      &lt;StackPanel&gt;
          &lt;TextBox x:Name="TextBox"/&gt;
          &lt;Button IsEnabled="False" Content="Disabled Button"/&gt;
      &lt;/StackPanel&gt;
  &lt;/ScrollViewer&gt;
  </code></pre>
  
  <p></p>
  
  <p>Setting IsFocusable="False" on ScrollViewer helps. But is it right workaround?</p>
