The Bugbug bot thinks this bug should belong to the 'Core::DOM: Editor' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Confirmed on Linux comparing copy and paste from Firefox and Chrome to gedit.

Carriage returns don't appear in the DOM naturally, so it seems the plain text serializer is bad at dealing with this.
