title: Dialogs not working in iOS 7 full screen web apps
body: <p>Web apps that have an icon saved to the home screen (mobile Safari - iOS 7 only) no longer seem to pause the thread when a dialog is in the method.
  For example an </p>
  
  <pre><code>'alert('something here')' 
  </code></pre>
  
  <p>just gets bypassed, and a </p>
  
  <pre><code>var a = confirm('Are you sure') 
  </code></pre>
  
  <p>always returns false for 'a' and does not present a dialog.  Dialogs are presented when the web page is not accessed from a homescreen icon.  This is only the case when the page is presented as a full-screen web app.</p>
  
  <p>I have not found any documentation to support this.  Am I missing something?</p>
