I cannot reproduce this here.

Emacs does not really know how to merge two menus that way.
What you have to do instead is have your text-local map hide the
buffer-local menu and replace it with another one (which has
the same name but another binding).
This is a limitation of the current code in keyboard.c, AFAIK.
