Prepare for React futures

I’m so happy to see how Slate has continued to grow and is so well maintained. 👍 I’ve finally had an opportunity to use it again, and I reached for it without hesitation.

One thing I have noticed is that warnings get thrown out when running Slate with React’s StrictMode enabled.

It would be great to compile a list of the things that need to be updated/refactored in order to get Slate lined up for the future of React.

Currently I see the following:

Warning: findDOMNode is deprecated in StrictMode. findDOMNode was passed an instance of Editor$$1 which is inside StrictMode. Instead, add a ref directly to the element you want to reference.

    in div (created by Content)
    in Content (created by Editor$$1)

The fix for this is detailed here.

Here is a demo showcasing Slate, whilst making use of the new Concurrent and Hooks features of React: https://codesandbox.io/s/qvoxpl3x4j

FWIW I think the plan is to make forwardRef the default behavior in future versions of React (see https://twitter.com/dan_abramov/status/1109512531209584640)

Would the solution to this be to keep a ref map for all of the nodes in the editor? 😬
