The following code may be useful to find out which is the element in charge of scrolling the viewport:

function getScrollingElement() {
  var d = document;
  return  d.documentElement.scrollHeight > d.body.scrollHeight &&
          d.compatMode.indexOf('CSS1') == 0 ?
          d.documentElement :
          d.body;
}

it must be invoked before performing the actual scroll operation instead of during onload or DOMContentLoaded since the content may change later. See here for a cross browser example using the above code:

This code will work when the bug will be fixed as explained in W3C CSSOM View specifications.
