[Dovecot] shared namespaces with common prefix prefix

Can shared/public namespaces' prefixes have a common prefix? :)

namespace public { separator = / prefix = zz/shared/ location = maildir:/var/maildir/shared:INDEX=/var/maildir/%n/shared subscriptions = no } # to share other employees mailboxes (term'd or admin access) namespace shared { separator = / prefix = zz/shared/%%u/ location = maildir:/var/maildir/%%n:INDEX=/var/maildir/users/%%u subscriptions = no list = children }

Since I added the shared namespace, I can no longer access the public namespace. The folders show up but then trying to access one gets the error that the mailbox doesn't exist.

If they can't have a common part of the prefix, is that an IMAP limitation or could dovecot conceivably handle it?
