title: Why does my Hub always show the turnstile animation when I navigate (back) to the page?
body: <p>I've got a simple page set up:</p>
  
  <pre><code>&lt;Page ...stuff goes here...&gt;
      &lt;Hub&gt;
          &lt;Hub.Header&gt;
              &lt;views:HubHeaderView /&gt;
          &lt;/Hub.Header&gt;
          &lt;HubSection x:Name="PrimaryViewSection"&gt;
              &lt;DataTemplate&gt;
                  &lt;views:PrimaryHubView /&gt;
              &lt;/DataTemplate&gt;
          &lt;/HubSection&gt;
      &lt;/Hub&gt;
  &lt;/Page&gt;
  </code></pre>
  
  <p>Every time I navigate to this page, on first view and when I hit the back button after further navigation, I always get the turnstile animation. It looks really ugly since the <code>Hub</code> control is so wide. The problem is, I've tried clearing all the <code>Transitions</code> and <code>ChildrenTransitions</code> that I can find, and none of them seem to be the right one. What do I have to do to make the <code>Hub</code> not animate like this?</p>
