При использовании DiffUtil и анимаций adapterPosition может возвращать NO_POSITION или некорректное значение. bindingAdapterPosition учитывает текущее состояние адаптера

Каждый раз вызывается findViewById для поиска title, statusIcon и avatarImageView, хотя часть View уже найдена в конструкторе. Это неэффективно при прокрутке списка.
Вынесите поиск всех View (title, statusIcon, avatarImageView) в конструктор ChatViewHolder и сохраните их как поля класса. В bind() просто используйте уже найденные ссылки. Это стандартная практика оптимизации ViewHolder в RecyclerView.
