Creating code blocks unexpectedly creates (nested) code inlines

[jeromesimeon]

Describe the bug
Creating a code block does not create a code block but different levels of code inlines.

To Reproduce
Steps to reproduce the behavior:

1. Go to the markdown editor
2. Select a paragraph
3. Click on 'code' button
4. It does not create a code block, but some code inlines

Expected behavior
Selecting a paragraph (or multiple paragraphs) and clicking code should create a code block.

The corresponding Slate does not include code blocks at all, just marks with type set to code.

I don't think I can recreate this, is it solved?

I can try it again

It does not look fixed. I just think it's not that easy to see since code blocks look exactly as multiple paragraphs containing code inlines.

This might have to be generalised into "Support for Code block". I am not able to change a code block into a paragraph.

Also maybe the current behaviour is ok, even if it doesn't create code blocks.
