Title: Remove wrong HTML in calendar form field

Whatever these 2 lines are supposed to do, they have no business in the form field. If those are actually needed, they should be part of JHTML::calendar() and not here.

There is no HTML5 neither in the form field, nor in the JHtml::calendar() method.
