When initiated by MediaController, it should be possible for `MediaSession` to pass `MediaItems` to the `Player` if they have `LocalConfiguration`. In such case, it is not required to override `MediaSession.Callback.onAddMediaItems`, because the new current default implementation will handle it.
However, in other cases, MediaItem.toBundle() will continue to strip the LocalConfiguration information.
