Unexpected return from .contains when using ':first-child' selector

[culyun]

Environment

IE 6.0.2900.2180.xpsp_sp2_gdr.080814-1233 FF 2.0.0.32 Opera 9.62

Example

jQuery(document).ready(function() {

var html = ; html += '<form class="the-form">'; html += 'silly text'; html += '<img class="silly-img" src="potato.jpg"/>'; html += '</form>';

create an unattached dom wrapped inside a jquery

var dom = $(document.createElement('div')).html(html); var form = dom.find('.the-form');

As I read the documentation the output from the use of ':first' and 'first-child' selectors, should be identical in the case of a trivial (single-element) selection set

var firstElem = form.children(':first'); ok, returns silly-img var firstNode = form.contents(':first'); ok, returns 'silly text'

firstElem = form.children(':first-child'); ok, returns silly-img firstNode = form.contents(':first-child'); fail, returns silly-img. should return 'silly text'

}

:first-child only matches elements, not text nodes - this is expected with the CSS Selector specification.
