A feature? I don't know, but It feels odd when such things are happening 
to me :)

All other clients sync correctly the "read/unread" status, so I can't 
think this as a feature. It seems like some kind of inconsistency 
between devices that are supposed to be in sync via the imap protocol, 
but their are not.
