Thanks, this use case now works.

However, I'm not sure I understand what happens when I edit the
kill-ring entry before hitting RET, which gets it inserted.  Is the
edited entry added to the kill-ring?  It looks like it isn't, because
the next C-y inserts the last kill-ring entry, i.e. neither the
original entry I edited nor the edited entry actually inserted.  Why
does the kill-ring-yank-pointer gets reset to the front of the
kill-ring in this case?
