background-position: center center;will not work. It's compiled to background-position: 50%;
But at that moment you will miss the y value of the function positionToNegativeMargin where the browser returns an error. (only in IE).
The solution will be to set y = x when y is undefined.

Thanks for the bug report! Can you please provide a few things:

  • failing demo (using a service like JSFiddle or JSBin)
  • version of failing browser
  • proposed fix (using a service like JSFiddle or JSBin)

failing demo http://codepen.io/JroonA/pen/Vjjaem?editors=1111 (fiddle issue #60) and change background-position to center center instead of 50% 50%.
Browser MS IE11

The solution will be to set y = x when y is undefined.

Non-numeric background-position is currently unsupported. #38 would be the issue to watch for changes to this.
