As a workaround (if this turns out to be a Dovecot bug) -
- you could use STATUS instead.
It would be several commands, one per folder, so you'd want to send them
pipelined for performance.
I've done this before in an email app I worked on and haven't seen any issues
with Dovecot or any other server (e.g. Gmail, Cyrus, Fastmail ...)
