click_hidden doesn’t account for CSS :hover pseudo class

[polarblau]

If the element in question is shown via CSS e.g. through a :hover pseudo selector or any JS event other than mouseenter (hover), the current implementation will fail.

Here's an example:

<a href="#"><span>Foo</span>Bar</a>

a span { display: none; } 
a:hover span { display: block; }

$('a').trigger('mouseenter');

This will have no effect. Better would be probably an implementation which is independent from how the element is hidden and shown, e.g. using $.fn.show().
