Title: Remove wrapping div with inline styles for hidden form fields.

The div was added for XHTML 1.0 Strict compliance and the inline
styles were added to work around Firefox 12 not submitting invisible
inputs. With HTML5 as the default doctype and Firefox 12 market
share at 0.21% the time has come for these to go.

Fixes #11407
