$animate.cancel does not have the expected behavior - angularjs

Question

I m trying to use the cancel feature of angularJS's $animate : https://docs.angularjs.org/api/ngAnimate/service/$animate with the latest stable version: 1.3.2
But either I have failed to understand what it is supposed to do or it does not have the expected behavior:
I have a custom animation as such:
var animationPromise = $animate.addClass(element, 'move-items-animation', {
from: {
position: 'absolute',
},
to: {
left : item.x + 'px',
top : item.y + 'px'
}
}).then(function(){
element.classList.remove('move-items-animation');
});
$timeout(function(){
$animate.cancel(animationPromise); //promise.$$cancelFn is not a function`
}, 300);
So a basic CSS transform. In addition to this I have the following CSS transition:
.move-items-animation-add-active{
transition: 1s ease-in-out;
}
So first weird behavior: I get the error promise.$$cancelFn is not a function coming from https://github.com/angular/bower-angular-animate/blob/master/angular-animate.js#L1233
See fiddle: http://jsfiddle.net/q1L9ycsd/6/
So I changed slightly the code :
var animationPromise = $animate.addClass(element, 'move-items-animation', {
from: {
position: 'absolute',
},
to: {
left : item.x + 'px',
top : item.y + 'px'
}
});
animationPromise.then(function(){
// After canceling this is executed
element.classList.remove('move-items-animation');
});
$timeout(function(){
$animate.cancel(animationPromise); // The animation goes on
}, 300);
So now I don't have that error but the animation is not stopped but the callback from the animation is executed. Does this mean that I have to manually stop the animation there?
See fiddle: http://jsfiddle.net/524nfp0o/2/
I have also try to cancel the animation in a separate event with the same result, see fiddle: http://jsfiddle.net/0o24zw02/
So
1. Why the error in the first fiddle?
2. How to actually stop an animation?
Thanks!

It works in 1.4, I'm not seeing it documented in 1.3 $animate:
Not documented: https://code.angularjs.org/1.3.20/docs/api/ng/service/$animate
Documented: https://code.angularjs.org/1.4.0/docs/api/ng/service/$animate
I was actually having this issue with your library and your result is the only one :)
