     <p>How <code>:hidden</code> is determined was changed in jQuery 1.3.2. An element is assumed to be hidden if it or any of its parents consumes no space in the document. CSS visibility isn't taken into account (therefore <code>$( elem ).css( "visibility", "hidden" ).is( ":hidden" ) == false</code>).
