Graph disappears when in VR mode?

Hi, after many attempts, I was finally able to get VR working with another github project quite easily (https://github.com/mister-blanket/blood-lines)

But, now I am facing another issue: when I click on the Enter VR button, the 360 video appears correctly but the graph does not, at all. If anyone has any ideas at all, that would be super appreciated as I'm not sure what the issue is.

I'm wondering if this is a container issue? Here is my code:

<!DOCTYPE html>
<html lang="en">
<head>

//font
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <link href="https://cdn.rawgit.com/mister-blanket/portfolio/master/css/fontawesome/css/all.css" rel="stylesheet">
  <title>Blood Lines</title>

</head>

<body>
  <div id='root'></div>
//container for 360 video
  <div id="container"></div>
    <canvas data-engine="three.js r135" width="563" height="706" z-index="-1"
    style="display: block; width: 563; height: 706;"></canvas>
</div>

//360 video
<video id="background-video" autoplay loop muted>
 <source src="http://altartnet.com/~malani/Test360VRCam_CorrectFPS_1.mp4" type="video/mp4">
</video>

</body>

</html>

Thank you
