[Plugin: Info Box on New Post/Page Editor] Carriage return not working

I know this plugin is old but i’ll give this a go:

I’m trying to get a carriage return to show up with my text in the info box. Using br/ does not work, nor does p or any other tag.

Any ideas on how to enter a carriage return?
