title: Videojs youtube video not playing in an iframe in desktop Chrome
body: <p>I'm loading a <code>/videojs-youtube/examples/simple.html</code> example page from the <a href="https://github.com/videojs/videojs-youtube" rel="nofollow noreferrer">https://github.com/videojs/videojs-youtube</a> in an iframe on a different domain. When I do this the video doesn't play and the loading indicator spins and doesn't stop. I see no javascript errors in the dev console. When I access the same file directly the video plays without any issues.</p>
  
  <p>The issue occurs only in the latest desktop Chrome 72.0.3626.109. Other browsers don't seem to have it.</p>
  
  <p>Here's a screen capture of how it looks like on my side:</p>
  
  <p><a href="https://www.youtube.com/watch?v=QBmre1vaLwI" rel="nofollow noreferrer">https://www.youtube.com/watch?v=QBmre1vaLwI</a></p>

  <p>Iframe source: <a href="https://alxd.ru/videojs-youtube/" rel="nofollow noreferrer">https://alxd.ru/videojs-youtube/</a></p>
  
  <p>Page source code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;

  &lt;/head&gt;
  &lt;body&gt;
    &lt;video

      data-setup='{ "techOrder": ["youtube", "html5"], "sources": [{ "type": "video/youtube", "src": "https://www.youtube.com/watch?v=xjS6SftYQaQ"}] }'
    &gt;
    &lt;/video&gt;
  
    &lt;script src="./video.js/dist/video.js"&gt;&lt;/script&gt;
    &lt;script src="./Youtube.min.js"&gt;&lt;/script&gt;
  &lt;/body&gt;
  &lt;/html&gt;</code></pre>
  </div>
  </div>

  <p>I'll appreciate any help.</p>
