Field is missing border.

It would be nice if the code field had a had a border keeping consistent with all other form fields in Wordpress. At the moment it feels more like descriptive text rather then a field you can edit.

This becomes confusing when it's empty, where a novice user may not know they can click in the blank area to populate.

As a follow up, I've added the field border via CSS with add_action and it looks so much more like an actual field rather then the message block. Would be great if this was built-in.
