Krzysztof Kotlarek 1921538faa FIX: show new/unread button when a new topic or post is created (#8576)
There is a problem that if you read all messages, even when a new one
arrives, the button on the top is not showing.

This is because once the button got `hidden` class, a label under is
properly updated, however, the class is not removed.

Therefore, I added computed isHidden function which is recalculated when
`count` change.
