begin() is not called when duration: 0

[manake]

The documentation says:

Both begin() and complete() callbacks are called if the animation's duration is 0.

But in the actual code begin() is never called for duration: 0 (for duration: 1 it works):

{
    duration: 0,
    begin: function(){
        console.log('test', this); // Doesn't work
    },
    complete: function(){
        console.log('test 2', this); // Works
    },
},
