Description
What should the :visible test return when the parent element is hidden(display: none)?
The result in safari is different from that in other major browsers.

This inconsistency also affects methods using .filter(':visible') such as .hide().

The solution to this issue is best dealt with on a case by case basis because of the performance hit. One would need to walk up the DOM tree and check the parents for visibility in Safari.

This bug/feature causes another issue when using the .resizeable() function of jQuery.ui
If the parent div is display:none, then
$('#div1').resizeable({ proportionallyResize: ['div'] });
On resize the internal div is incorrectly resized. This is due to an incorrect assumption that when $(an_element).is(':visible') returns true, $(an_element) has an outterWidth and outterHeight. See http://dev.jquery.com/browser/tags/1.2.1/src/core.js#L647

Fixed in SVN rev [6210].
It isn't jquery's fault. It is caused by that in safari window.getComputedStyle($('#div1')[0]).display == 'none'. The behavior of .is(':visible') in safari is correct conceptually. But I think, for most of programmers, the behavior in firefox/opera/ie is more desired.
