* Drop the ugly height: 100% hack and do it properly and remove TODO
* after( $suggestions.show() ) seems to not work as expected in recent
jQuery versions. Changed it to manipulate the presence of 'hide'
class properly.
* Consistency fix in a comment
* Fixed a bug where creating multiple ULS instances would break the
"no search results" functionality. This is because we were appending
a jQuery element wrapped in a $(). This is obviously a no-op and a
regression when the template actually was a string and not jQuery.
Fixed by using clone() on it.
