Okay, could you try the attached patch? It is based on current master
and tries to look up the article number (uid) in NOVCACHE and falls
back to UID SEARCH when the message is not cached.
To make a message enter Gnus' cache you might to modify
`gnus-cache-enter-articles'. The cache setting I used to test the
patch are:
,----[ gnus.el ]
| (setq nnimap-nov-is-evil nil)
| (setq gnus-use-cache t)
| (setq gnus-cache-enter-articles '(ticked dormant unread read))
`----
NOTE: This patch is deliberately not attached as text/plain to avoid
the patchtracker catching it (no proper commit message and all).
Best,
