Currently delegates do not get deleted when removed from models. Due to the complexity of drag state and other objects, we can't simply delete the delegate when removed from the model because they might still be involved in animations or other state at the time of removal. Use smart pointers to have the delegate objects deleted instead. QML unfortunately doesn't support QSharedPointer, so we need to expose raw pointers to it.
