Already animated elements don't fire complete callback

[grrowl]

When an element (or set of elements) is already hidden and you call fadeOut(), jQuery will no longer file the 'complete' callback. The following code replicates the issue:

var myElem = $('<div>Hi, I'm an element!</div>');
myElem.appendTo('body').hide();

myElem.fadeOut(function () {
  alert('I've finished fading out!'); // this will never get executed
});

Issue also exists for a visible element and calling fadeIn();

Doesn't call the step callback either.

I think my patch concerns the same issue and might do the trick :
