reactScrollbar ScrollArea doesnt work under IE 11

Cheers.

when rendering page in Internet Explorer 11 invariant.js throws error:

e.render(): A valid React element (or null) must be returned. You may have returned undefined, an array or some other invalid object.

chrome, firefox, safari, opera work just fine; main.js as basic as it gets:

import React from 'react';
import {render} from 'react-dom';
import ScrollArea from 'react-scrollbar';

render(<ScrollArea><div>hello</div></ScrollArea>, document.getElementById('app'));

When i was looking for solution i managed to make a scenario (in real app, with router.js) when i saw in ReactReconciler:

Unable to get property 'getNativeNode' of undefined or null reference.

But i forgot how exactly and cant provide info how to reproduce it anymore.

On above i've found https://github.com/facebook/react/issues/6271, https://github.com/facebook/react/issues/6246 may those be connected to this issue?
