title: MouseBinding WheelClick not pass through
body: <p>I am using the following code in xaml to add a command to a mouse wheel scroll event. It is a item inside a itemscontrol. The command can be correctly triggered. However, the wheel scroll event seems not passed to its parent any more. So when I scroll the mouse wheel, the items inside the itemscontrol won't move anymore. How to solve this issue? </p>
  
  <pre><code>&lt;UserControl.InputBindings&gt;
      &lt;MouseBinding Gesture="WheelClick" Command="{Binding MyMouseWheelCommand}"/&gt;
  &lt;/UserControl.InputBindings&gt;
  </code></pre>
