Has attribute "selected" shows different behavior with context vs. without.

I've tracked this bug down to the following problem: Place a <select> element into an HTML page with an <option> element. Do not add the "selected" attribute.

var sel = $('select');

$('select option[selected]'); $('option[selected]', sel);

Both of these return different results. Using context contains the option element even though there is no selected attribute. Using Firefox 3.5.3 on Ubuntu with Firebug 1.5.3.

​http://jsfiddle.net/dmethvin/UtAus/ I get consistent and correct results with Firefox 3.5, Opera 10, Chrome 7, and Safari 5. However, IE8 does not correctly return a selected option for #tock. This behavior seems to have changed between 1.4.2 and 1.4.3 only for IE.

This is an issue with IE8's qsa. I don't know why it messes up, but it is not really an issue with Sizzle. I don't think we can fix it without defacing qsa Sizzle. It would mean an additional support test and a solo attribute check just for [selected] in IE8. I don't think we want the performance hit so I suggest this should stay the way it is. This works in all browsers if selected is set to "selected":

[selected="selected"]

Closing patchwelcome, but I'm of the opinion the extra code is not worth it.
