title: Video is not show inline when using the method "playsinline"?
body: <p>help, I'm adding an instructional video before the game starts, but it opens the native player, it can't play it online.</p>
  <pre><code>    video = game.add.video('space');
      video.addToWorld();
      video.unlock();
      video.play(true);
      video.playsinline(true);
  </code></pre>
