Incorrect MutableObservableArray difference

[krotoff]

Hello.

I have an issue with diff and patch calculating. I receive nothing in these properties when have changes in the array.
To check this, I have added zipPrevious and it shows that I have real changes, but not diff and patch.

viewModel.bnd_items
  .zipPrevious()
  .observeNext { (old, items) in
    print(items.diff, items.patch, old?.collection == items.collection) 
    // Inserts: [], Deletes: [], Updates: [], Moves: [] [] false
  }
  .dispose(in: disposeBag)
