Description

Working test case: http://jsfiddle.net/hd4NK/

In Opera 10.63 the following return different length collections:

    $("#con").find(".required, #bar, #btm :input");
    $("#con").find("#btm :input, .required, #bar");

when querying the following mark-up

<fieldset id="cont">
	<div id="top">
		<input type="text" class="required"  />
		<input type="text" id="bar"  />
	</div>
	<div id="btm">
		<input type="text" class="required2"  />
		<input type="text" id="foo"  />
	</div>
</fieldset>

All other browsers tested (FF 3.6, IE8, Safari5, Chrome8) return expected results. Same issue is in 1.4.4 too.

In 1.4.2 all browsers return the same results.

Yeah, the bug appears to be that qSA isn't throwing for an unsupported pseudo-class if there is a valid part first. So document.querySelectorAll(':foo, input') will throw, but not document.querySelectorAll('input, :foo').

Fair enough. Interesting that is worked OK in 1.4.2 which indicates to me that it's maybe not a bug in Opera but I haven't dug deeply into this. Maybe jQuery wasn't using native qSA in 1.4.2 for Opera.

No it is a bug in Opera. There were some internal changes from jQuery 1.4.2 to 1.4.4 which caused this to become apparent.

I think we clearly established that this was an Opera bug we can't work around, and miketaylr's buddies are hot on the case.
