Replace broken on css return value

[DumpsterDoggy]

The following test works in 1.3.2:

test("can set and retrieve width", function() {
	var width = $("<p/>").css({width:100}).css("width").replace(/px/,"");
	equals(width, 100);
});

but fails in 1.4a1 with the message:

$("<p/>").css({width: 100}).css("width").replace is not a function
