I have never seen it work that way. Anyway, nothing of what I have
described changes if you use gui=reverse instead of gui=NONE,reverse.

Fine, but my question is different: is it true that (1), (2) and (3)
above always produce the same result? I used to think that the answer
was positive, at least for (1) and (2), but I have encountered a case
(using fg in iVim) in which there is a difference between (1) and (2).

Also, in a very old thread entitled "[BUG] Background is reset when
ctermbg for `Normal' group is redefined", Bram wrote the following
reply:

which makes me believe that (2) is the way to go. But that was in 2006,
and I don't know whether the advice is still valid.

Life.
