The control was changed, to have a new property as discussed in the forums.  Backwards compatibility is the main reason for this.  Depending on the use for the control the property may be set a certain way.  For example, the Module title most likely will stay rendering as a SPAN (we don't want line breaks here), while the text/html will render as a DIV.  We decided to shy away from the css-hacks that would be required to always render as a div.
