TYPO3 Core

When using the form wizard to edit a form containing fields with multiple values such as radio buttons or selects, newlines are inserted after saving the form.

Example radio buttons before using the wizard:

Question | *Question=radio | Yes, No

After saving form using the wizard:

Question | *Question=radio | Yes,
No

This issue doesn't occur using TYPO3 4.5.x and to clarify: we're using the old form extension, not the new one.
I've added a screenshot to show how this looks front end.
