title: iframe does not work on iPhone when the webpage is saved to homepage
body: <p>I have a video player on a webpage using an iframe and javascript (parts of the code shown below). Everything works fine on my laptop and on safari on an iPad with iOS8. However if I add the webpage to the homescreen and open the webpage from the homescreen, the video won't load. I made a quick jsbin with everything and it works on iOS 8 from the homescreen so it shouldn't be a problem with the code itself. Is there anything differently that safari does when the link is opened from the homepage?</p>
  
  <p>html:</p>
  
  <pre><code>&lt;iframe class="youtube-player" type="text/html" width="320" height="192" id="YouTubePlayer"&gt;
  &lt;/iframe&gt;
  </code></pre>
  
  <p>javscript:</p>
  
  <pre><code>url = 'http://www.youtube.com/embed/5JJ983bxFGU';
  $('#YouTubePlayer').attr({
          src: url
  })
  </code></pre>
