SwiftUI + Core Data: animation on Core Data object properties does not work.

I want to animate part of my View when a property on a Core Data object is updated. These Core Data objects are ObservableObject so when I update a property on the object using a binding (like a Toggle) or a Button, I expect it to animate. But it’s not working. If I toggle a boolean property on my object, there is no animation. If I change a Boolean value in a Button using a withAnimation block, it does not animated. If I do the same with an ObservableObject class (boolean is a Published property), the animation is respected. A workaround is to use another property (isFavoriteWrapped) and to call objectWillChange.send() manually in the property setter. But this feels wrong. The expected behaviour should be similar to what we see with the ObservableObject.
