Hello !

I'm trying to use this component on Safari, version 12.0.2 on MacOS 10.14.2.
The <google-youtube> is present into HTML DOM but nothing is displayed on the webapp. I have not any error into the JavaScript console.
On Google Chrome, it's working fine.

The full html:

<link rel="import" href="bower_components/google-youtube/google-youtube.html">
<google-youtube class="googleYouTube" video-id="l_BWeuz1k4c"></google-youtube>

CSS:

.googleYouTube {
  display: block;
  width: 480px;
  margin: 0 auto;
  height: 270px;
}

There is specs to apply to be able to work on Safari brower ?
