Uncaught TypeError: Right-hand side of 'instanceof' is not an object #76

Context

Using this library, when I try to mount (using Enzyme) a react component it throws an error on checking that the target element is SvgElement or not.

The same issue was fixed here: https://github.com/atlassian/react-beautiful-dnd/pull/1251
