title: UIAutomation Nested Accessibilty Elements Disappear from Hierarchy
body: <p>I have a view with two subviews a button and an Image, I turn on accessibility and set the label on the subviews and I can see the hierarchy by calling </p>
  
  <pre><code>UIATarget.localTarget().frontMostApp().mainWindow().logElementTree();
  </code></pre>
  
  <p>I get the following for example:</p>
  
  <blockquote>
    <p>1 Window</p>
    
    <p>2 My View</p>
    
    <p>3 My Button</p>
    
    <p>3 My Image</p>
  </blockquote>
  
  <p>If I then turn on accessibility and set the label for my parent view I can no longer see my button and image anywhere in the hierarchy.</p>
  
  <p>I just get:</p>
  
  <blockquote>
    <p>1 Window</p>
    
    <p>2 My View</p>
  </blockquote>
  
  <p>Why have my views disappeared?</p>
