title: Full Screen event on Touch not working on Chrome
body: <p>In my mobile app I want to toggle full screen when user is swiping up.<br>
  So when <code>touchend</code> event is triggered I'm calling  <code>document.documentElement.webkitRequestFullScreen();</code><br>
  The problem is that it doesn't works for me in mobile Chrome 56+.</p>
  
  <p>Here is example.

  <p>The interest part is: this issue appearing only when you make touchmove between touchstart and touchend.</p>
  
  <p>In console I've got an error:</p>
  
  <blockquote>
    <p>Failed to execute 'requestFullscreen' on 'Element': API can only be
    initiated by a user gesture.
    document.documentElement.webkitRequestFullScreen();</p>
  </blockquote>
  
  <p>Does anyone know how to struggle it?</p>
