I’m having the same issue.
I also noticed that besides the paragraphs being inserted, the link itself gets wiped out in the editor when I press the Update button, though it appears on the front end. Of course, if you Update it twice, it then disappears from the front end as well since it’s no longer recognized by the editor.
Fernando’s workaround was successful for me, but impractical for clients. Hopefully this gets solved soon.
