The editor needs to be updated to use Slate 0.50.x. This is a major release of Slate with many breaking changes.

This work is underway in the slate-0.50.x-hack branch. Note that you also need to npm link to the accordproject/markdown-slate on the slate-0.50.x branch.

If you want to paste HTML img tags you will also need to npm link to @accordproject/markdown-html on the slate-0.50.x branch.
