Imagine you have a default like myArray : []. Then, you initialize a model passing an initial value of myArray: [1,1,2,3]. The result of model.get('myArray') is not [1,1,2,3] but it is [1,2,3].
myArray : []
myArray: [1,1,2,3]
model.get('myArray')
[1,1,2,3]
[1,2,3]
This issue is caused by this function:
combine = function(key) { return source[key] = _.union(destination[key], source[key]); };
As a metter of fact, _.union returns all unique items inside the two arrays. So, if my destination[key] array is not unique the result will be wrong.
