Look at the following code:

$("<div>").queue(function(next) {
    console.log("test");
    next();
}).show(100, function() {
    console.log("show callback");
}).queue(function(next) {
    console.log("test");
    next();
});

I would expect the output to be "test" then "show callback" then "test" but it seems that the output is "test" "test" "show callback" which seems backwards to me.

This bug (?) seems present all the way back to 1.4.4.
