Scrollbar doesn't work inside iframe

Scrollbar doesn't work inside iframe. It throws this exception:

TypeError: Object.defineProperty called on non-object

The problem is in this line:

https://github.com/malihu/malihu-custom-scrollbar-plugin/blob/master/js/uncompressed/jquery.mCustomScrollbar.js#L1217

$(document).add(eds).bind("mousemove."+namespace+" pointermove."+namespace+" MSPointerMove."+namespace,function(e){

In iframe eds variable equals [true].

eds=o.advanced.extraDraggableSelectors ? $(!_canAccessIFrame() || top.document).add($(o.advanced.extraDraggableSelectors)) : $(!_canAccessIFrame() || top.document);

jQuery version: v3.1.0
Demo (look in the browser console): https://jsfiddle.net/dpz1a7dx/3/
