react-dnd in 2.7 is a complete disaster

react-sortable-tree now seems to depend on two different versions of react-dnd (7.x and 9.4). And in 9.4 the default module format is no longer common-js, which breaks... everything.

I can see you've worked around some issues in react-dnd with module name mapping in package.json.

But... now if I create a new react app using react-sortable-tree I seem to be lost in configuration hell. Looks like I'd have to eject my react app or something to implement the same jest configuration you have used to make it work for you.

I've spent 2 days now trying to figure out how to upgrade react-sortable-tree from 2.6 to 2.7 in my app. Is anyone else having the same problem?
