Uncaught Error: removeComponentAsRefFrom(...)

Multiple React-hot-loader: unable to merge top-level components, followed by

Uncaught Error: removeComponentAsRefFrom(...): Only a ReactOwner can have refs. You might be removing a ref to a component that was not created inside a component's render method, or you have multiple copies of React loaded (details: https://fb.me/react-refs-must-have-owner).

In the same time - it is working as expected, doing it's work.

4.0.0-beta.20 - the same
4.0.0-beta.19 - the same
4.0.0-beta.15-19 - nothing works, everything got unmounted.

4.0.0-beta.13-14 - less of unable to merge, all about low-level components. Working.

React 16.2.0 - the same unable to merge, but no errors.

Code to reproduce: not extracted yet. Just filling the issue.

In all the cases unable to merge solved by sub-renders. This is just a parasite error message for React 15. Will try to solve the merge problem, as long it is a single pattern - I was just happy to have in my personal project.

The only thing we did not test - html elements nested in html elements nested in html elements, and no or them to be actually "replaced".
