I think I understand what's going on.  In Gnus, there's no such thing as
"ticked and unread": Everything that's \Flagged in the IMAP server
becomes read in Gnus.  So when you remove the tick (i.e., \Flagged),
Gnus will propagate that change to the IMAP server, but since it thinks
that nothing has changed WRT readedness, it doesn't send that
information to the server...

I'm not sure what the best way to fix that is...
