I am not able to reproduce this with zsh-, at
least not with only:

zstyle '*' format %d
zstyle ':completion:*' list-dirs-first true
zstyle ':completion:*:*:*:*' list-suffixes yes
setopt globcomplete

This I am able to reproduce with the settings above.

However, if I invoke _next_tags at that point, I get:

% ls a/b/d/e/g
b1/d/e/g  b2/d/e/g

So the results have been correctly completed and added, they're just
not in the tag group where they appear on the first attempt.

The settings of list-dirs-first and list-suffixes have no effect on
the tag to which the matches are added in this case.  It's all down to
globcomplete.  _next_tags works here, too.

When globcomplete is set, the following differences occur:
_path_files line 251 forces menu=yes
_path_files line 737 sets SUFFIX=*/d/e/g*
_path_files returns false to _files line 119, so ret=0 is not done at line 120
_files line 109 invokes _tags which calls comptags -N
_files returns false to _arguments, so ret=0 is not done at line 465
_arguments line 467 sets alwopt=yes
_arguments line 538 test is true, so 543-551 run compadd
_arguments line 586 is false, returns false to _dispatch, no ret=0 at line 63
_dispatch returns false to _complete, no ret=0 at line 117
_complete returns false _main_complete

As you mention in a later message on this this thread, one problem is
at _path_files line 737, that suffix will never match given that the
/e/ path segment is ambiguous.  Using :gs as you suggested resolves
everything after that, but introduces a new difference at
_main_compete:411, where compstate[pattern_match]='*' and
unambiguous_cursor=8 (instead of 4 in the noglobcomplete case).  That
seems to go along with having forced menu completion on, but it seems

Try ${Uopt} instead of -U there, and see if that makes any difference?

I don't seem to be able to re-create the setup for your "ctrl-g
toggling of behaviour" incident.  Can you specify?
