Error: Cannot resolve a DOM node from Slate node: {"text":""}

[peterstory]

Describe the bug I was creating a post in the markdown editor. I typed shift-return to create a line break instead of a paragraph.

To Reproduce Type shift-return to create a line break instead of a paragraph. Then delete the line break, and create a paragraph break instead. Decap will crash.

Expected behavior
