Description

Hi,

not sure it's a real bug but I was kinda expeting this to work : $('tr[id="foo"][style="display:none"]:first')

That would be selecting the first tr which name start with foo and has display style set to none.

Happens both in Firefox 5 and Chrome 13 : http://jsfiddle.net/d4QFg/

Another doubt is the list obtained with $('tr[id="foo"][style="display:none"]') sorted. I'm not sure that's always the case, hence the interest in a working :first selector chaining.

Also, http://api.jquery.com/first-selector/ has information regarding the performance losses you suffer with the :first selector.

The :first pushes Sizzle into the JavaScript code path rather than querySelectorAll. The JS path prefers the elem.style *property* (which is a CSSStyleDeclaration object) over the string style *attribute* of the element.

This started working when jQuery.attr was plugged into sizzle, but now works in an independent Sizzle.
