title: Closed VisualState for ComboBox in Windows 10, animations not played
body: <p>I have a problem with <code>Closed</code> VisualState for <code>ComboBox</code>. Animations in <code>Closed</code> state are being played only for the first time.</p>
  
  <ul>
  <li>ComboBox opened <em>for the first time</em> [all animations OK]</li>
  <li>ComboBox opened <em>for the second time</em> [no <code>Closed</code> animations]</li>
  </ul>
  
  <p>Here's XAML I'm using:</p>
  
  <pre><code>&lt;VisualStateGroup x:Name="DropDownStates"&gt;
      &lt;VisualState x:Name="Opened"&gt;
          &lt;Storyboard&gt;
              &lt;SplitOpenThemeAnimation ClosedTargetName="ContentPresenter"
           OpenedTargetName="PopupBorder"
           ClosedLength="0"
           OpenedLength="{Binding TemplateSettings.DropDownOpenedHeight, RelativeSource={RelativeSource Mode=TemplatedParent}}" /&gt;             
              &lt;ColorAnimation To="Transparent"
                              Duration="0:0:0.1"
                              Storyboard.TargetProperty="(UIElement.BorderBrush).(SolidColorBrush.Color)"
                              Storyboard.TargetName="Background"/&gt;
                  &lt;DoubleAnimation Storyboard.TargetName="DropDownGlyph"
                               Storyboard.TargetProperty="Opacity"
                               To="0"
                               Duration="0:0:0.2"&gt;
                  &lt;DoubleAnimation.EasingFunction&gt;
                      &lt;PowerEase EasingMode="EaseIn" /&gt;
                  &lt;/DoubleAnimation.EasingFunction&gt;
              &lt;/DoubleAnimation&gt;
          &lt;/Storyboard&gt;
      &lt;/VisualState&gt;
      &lt;VisualState x:Name="Closed"&gt;
          &lt;Storyboard&gt;
              &lt;SplitCloseThemeAnimation ClosedTargetName="ContentPresenter"
            OpenedTargetName="PopupBorder"
            ClosedLength="0"
            OpenedLength="{Binding TemplateSettings.DropDownOpenedHeight, RelativeSource={RelativeSource Mode=TemplatedParent}}" /&gt;
              &lt;ColorAnimation To="#66D3D3D3"
                              Duration="0:0:0.1"
                              Storyboard.TargetProperty="(UIElement.BorderBrush).(SolidColorBrush.Color)"
                              Storyboard.TargetName="Background" /&gt;
              &lt;DoubleAnimation Storyboard.TargetName="DropDownGlyph"
                               Storyboard.TargetProperty="Opacity"
                               To="1"
                               Duration="0:0:0.2"&gt;
                  &lt;DoubleAnimation.EasingFunction&gt;
                      &lt;PowerEase EasingMode="EaseIn" /&gt;
                  &lt;/DoubleAnimation.EasingFunction&gt;
              &lt;/DoubleAnimation&gt;
          &lt;/Storyboard&gt;
      &lt;/VisualState&gt;
  &lt;/VisualStateGroup&gt;  
  </code></pre>
  
  <p>Could you give me some advise, what I'm doing wrong? Thanks!</p>
