title: RemoveStoryboard so that it animates back to original
body: <p>I have the following code:</p>
  
  <pre><code>&lt;DataTrigger.EnterActions&gt;
    &lt;BeginStoryboard Name="foo" Storyboard="{StaticResource FadeInCurrentStoryBoard}"/&gt;
  &lt;/DataTrigger.EnterActions&gt;
  &lt;DataTrigger.ExitActions&gt;
    &lt;RemoveStoryboard BeginStoryboardName="foo"/&gt;
  &lt;/DataTrigger.ExitActions&gt;
  ...
  &lt;Storyboard x:Key="FadeInCurrentStoryBoard"&gt;
    &lt;ColorAnimation Duration="0:0:0.2" To="#75BAFF" Storyboard.TargetProperty="(TextBox.Foreground).(SolidColorBrush.Color)" Storyboard.TargetName="MainText"/&gt;
  ...
  </code></pre>
  
  <p>The problem is that removing the storyboard is immediate, but I would like to have a 0.2 delay back to the original values. I do not see any properties to set the removal duration?</p>
