Conflict with react-dropzone

I realise that when I use `react-sortable-hoc` and I also have `react-dropzone` on the same page, the sorting doesn't work well (e.g. I cannot drag an item in between other items, I can only drag an item to the very top or to the bottom).

I guess the drag event is being triggered for both which is causing this hiccup. Is there a way to prevent this conflict?
