Explain the Problem

When reading news the unread counter becomes negative at the end.

From the code it checks the state of item.unread before decreasing the counter.

        [FEED_ITEM_ACTION_TYPES.MARK_READ](
                { commit, dispatch }: ActionParams<ItemState>,
                { item }: { item: FeedItem },
        ) {
                ItemService.markRead(item, true)

                if (item.unread) {
                        commit(FEED_ITEM_MUTATION_TYPES.SET_UNREAD_COUNT, state.unreadCount - 1)

                        dispatch(FEED_ACTION_TYPES.MODIFY_FEED_UNREAD_COUNT, { feedId: item.feedId, delta: -1 })
                }
                item.unread = false
                commit(FEED_ITEM_MUTATION_TYPES.UPDATE_ITEM, { item })
        },

So either the state for item.unread has not really been set yet or an API call in between has changed the state of the feed or item.

Also MARK_READ is called every time you click an item or if you use key navigation to go through the items. This should be avoided.

Since this is not reproducibly if I go fast through multiple hundred items it would be nice, if someone has the them behaviour, to post some info here.

How did you go through the news (key navigation, mouse scroll, cursor or pgdn scroll)? Did you click items? Did you scroll forth and back in the list? Ho many items where there approximately in the list?
