jQuery UI tooltip position different in IE and chrome

I am observing different positioning behaviour while using jQuery UI tooltip widget in MSIE 11 and Chrome 49.

If the page with the widget is scrolled in MSIE the tooltip is displayed on the wrong position:

Please see the jsfiddle in MSIE to demonstrate the issue.

    $(".helpIcon").tooltip({
      hide: false,
      show: false,
      position: {
        my: "right top+3",
        at: "right bottom",
        using: function(position) {
          console.log(position);
          $(this).css(position);
        }
      }
    });

I am doing something unexpected? Or is there a hack I need to apply?
