Dovecot FINs after sending "NO Not showing other users' quota"

[Gene Smith via dovecot]

When I do imap getquota on a shared folder I see the NO response. That's 
OK but then often dovecot disconnects (sends FIN) to the client right 
after this. The client acks the disconnect and creates a new connection 
and continues on.
Should dovecot disconnect after this type of imap "NO" response?
