When copying the shortcode in the builder it wraps it into <pre> tags and if they are not removed when pasting it somewhere, the chat layout will not wrap words at the end of the line anymore.
It happened to me and it happened to another user recently, maybe others have the same issue? Worth correcting IMO.

How do you do this actually? It never happened to me 🙂
