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.

@peterstory do you mind checking if the crash still happens in 3.2.1?

[peterstory]

@demshy With 3.2.1, I don't have any issues. Thank you for the fix!
