1. Go to https://www.tiptap.dev/api/nodes/hard-break/#hardbreak and select & copy the text in the example editor.
2. Inspect the content of the clipboard by pasting it here: https://evercoder.github.io/clipboard-inspector/
3. The clipboard content for format text/plain is

Hey, it’s the same behavior at https://prosemirror.net/ so it’s not a bug with tiptap itself.

What you can do for now is to define a custom renderText method for the HardBreak extension:

const CustomHardBreak = HardBreak.extend({
  renderText() {
    return '\n'
  },
})

That's an elegant solution. Thank you!

I decided to put that into the extension!

@philippkuehn How can we use it now in the extension? it says "Duplicate extension names found [hardBreak]"
