title: Fullscreen video in the Chrome webview
body: <p>I have a problem with webview tag in the Google Chrome Extensions. When I open some video on youtube and press "Full-screen" button it behaves differently depends on the video type.</p>
  
  <ol>
  <li>If video displays using video tag
  (<code>&lt;webview src="http://www.youtube.com/watch?v=zk0TpSX0tKE"&gt;&lt;/webview&gt;</code>), it opens video in full
  webview and markdown breaks. </li>
  <li>If video displays using flash player
      (<code>&lt;webview src="http://www.youtube.com/watch?v=1Vcgdl4xQ18"&gt;&lt;/webview&gt;</code>), it opens in
      full-screen and works fine.</li>
  </ol>
  
  <p>Is there any way to make a video tag full-screen feature works in the same way like flash player?</p>
