Allow linebreaks instead of paragraphs for copy-pasted code

Description

I am using medium-editor for my developing blog. I want to add code by copy-paste and then use prism.js to display it. Currently when I copy & paste code, each line is a new paragraph. This does not work with prism.js. I would need real linebreaks.

How can I change that if I copy multiple lines that they are not in multiple paragraphs, but just separated by \n? Is this configurable?

Steps to reproduce

1. Copy multiple lines in editor

Expected behavior: Lines should be seperated by new line

Actual behavior: Lines are seperated by paragraph

Versions

• medium-editor: 5.23.3
• browser: Firefox 91.0.2
• OS: Ubuntu 18.04
