Gutenberg: Paragraph Block: "Open link in New tab" option for link button doesn't save in draft

Steps to reproduce

1. Add a paragraph block
2. Select a word and turn it into a link clicking the link button
3. Save the draft
4. Click the word to edit the link
5. Select the option to open link in new tab

What I expected

This is a post edit and should trigger the Save draft option

What happened instead

It didn't trigger it and didn't save the option.
