Sorry, I'm still confused.  Again, checking this option:

>   [ ] tab-bar-format-menu-global
>           Show global menu on clicking the Menu button.

causes the tab bar to include a single tab called "Menu", and if I
click on that tab, I see the items from the global menu-bar.

In any case, I don't see the importance of the fine difference between
"menu items" and "menu items that represent tabs" in this case.
AFAIU, whatever menu is produced by that option is what's displayed on
the tab bar; the items in the menu are entirely up to the function
which produces the menu.  Isn't that right?
