This is weird - it's broken only when both styles are set:

zstyle ':completion:*:descriptions' format '%B%d%b'
zstyle ':completion:*:messages' format ':%d'

This exposes some general issue - I don't know which part inserts
unambiguous SUFFIX into the ZLE, but obviously it should be done only
when completeinword is set.

This is probably some deeper bug somewhere, still happens with --norcs
followed by settings from this thread.

In my solution compstate[old_list]=keep is set on second tab strike and
the colors are recalculated at this point; is it because this is done
AFTER "# Stuff we always do to clean up" which restores ZLS_COLORS?
Any way to simulate this for _oldlist?


And one more final note - I said all of those sacrifice pattern from ZLE
(which might get people angry if they loose some hand-crafted fine-tuned
one and are unfamiliar with undo), however without globcomplete this
pattern is also lost.
