Sandbox
https://www.slatejs.org/examples/richtext

Steps
To reproduce the behavior:

1. Go to https://www.slatejs.org/examples/richtext
2. Replace "A wise quote." with an empty line without formatting
3. Copy the whole textbox content
4. Paste into Microsoft Word
5. Turn on formatting marks
6. See that the empty line between "... middle of the page, like this:" and "Try it out for yourself!" was not pasted

Expectation
The empty line should be pasted

Environment

• Slate Version: latest (0.102.0)
• Operating System: Tested on macOS, Windows 10
• Browser: Tested on Safari, Firefox

Context
I tried to fix it locally and it seems to work when removing the data-slate-zero-width="n" data-slate-length="0" attributes from the leaf node but you won't be able to edit the text further afterwards
