(One of) the reasons this was breaking was because previously, the template used
by the animation pages didn't have an <html> or <body> element. So here I
changed this to access the correct element (instead of creating another raw-like
template that only had the body content like raw was before)

     initAnimation(animation);
   }
   request.send(null);
 }
 
 function initAnimation(animation) {
   while (animation.firstChild)
     animation.removeChild(animation.firstChild);
