Javascript Get Element At Point Outside Viewport

Is there something similar to document.elementFromPoint(x,y) that works for elements that are outside the viewport? According to the MDN docs for document.elementFromPoint() (https

Hey I had the same issue, where if the element is not within the current bounds of the viewport elementFromPoint will return null.

I find that you have to scroll to the element location to make it visible in the viewport and then perform the elementFromPoint.

(function() {
  'use strict';
  var api;
  api = function(x,y) {
    var elm, scrollX, scrollY, newX, newY;
    /* stash current Window Scroll */
    scrollX = window.pageXOffset;
    scrollY = window.pageYOffset;
    /* scroll to element */window.scrollTo(x,y);
    /* calculate new relative element coordinates */
    newX = x - window.pageXOffset;
    newY = y - window.pageYOffset;
    /* grab the element */
    elm = this.elementFromPoint(newX,newY);
    /* revert to the previous scroll location */window.scrollTo(scrollX,scrollY);
    /* returned the grabbed element at the absolute coordinates */return elm;
  };
  this.document.elementFromAbsolutePoint = api;
}).call(this);

You can simply use this command whenever the coordinates are absolute from the pageX,pageY.

document.elementFromAbsolutePoint(2084, 1536);

This code is also on GitHub packaged into a bower component for ease of including into projects.
