[UI] Update unread count bubble realtime whilst scrolling
It would be a great addition if the unread bubble at the top would update and mark toots as read while you scroll past them. This is inline with behaviour found in a lot of feed readers. This would need to take in account "fetch more toots" properly, and would also remove the "new" label on a toot upon scrolling past it.
