Delete forward on empty line before code block unwraps code line

[12joan]

Description

When deleting forward from an empty paragraph immediately before a code block, the first line of the code block is unwrapped. This makes it impossible to remove such a paragraph if the code block should be at the start of the document.

Steps to Reproduce

1. Go to platejs.org
2. Create an empty paragraph followed by a code block containing at least two lines
3. Place the cursor at the empty paragraph
4. Delete forward

Expected Behavior

• If the paragraph is empty, delete forward should delete it without affecting the code block.
• If the paragraph is non-empty, the current behaviour is acceptable.

This is consistent with lists:
