 * If the there are unread messages in the channel and the `VirtualizedMessageList` renders
 * messages created later than the last read message in the channel, then the
 * `UnreadMessagesNotification` component is rendered. This is an approximate equivalent to being
 * scrolled below the `UnreadMessagesNotification` component.
