Yes, thanks.  I didn't realize this is essentially
a duplicate.

Is this taken care of _generally_, as requested
in #39848, or is it just taken care of for items
in this menu?

If fixed generally, then I guess it can be closed.

However, I do have a remark about what I see in
Emacs 27 (a dev snapshot from 2019-12-28):

 <menu-bar> <options> <line-wrapping> <window-wrap> runs the command
 menu-bar--wrap-long-lines-window-edge (found in global-map), which is
 an interactive compiled Lisp function in 'menu-bar.el'.

 It is bound to <menu-bar> <options> <line-wrapping> <window-wrap>.

 (menu-bar--wrap-long-lines-window-edge)

 Wrap long lines at window edge.

Command `menu-bar--wrap-long-lines-window-edge'
is precisely the kind of command that a user
might use, either directly or in lisp code.

So I really don't see why it's considered
"internal" (double-hyphen name).

I also don't see why it's in menu-bar.el or
it has prefix `menu-bar-'.  There's nothing
menu-specific about it.

Not only that, but unlike what menu `Options'
has generally been for, this item does not
just toggle a single user option value.  It
toggles two options and turns off a minor
mode.

Perhaps there are other considerations, but
at least on the face of it this command (and
its sister commands here) doesn't seem to
belong in menu-bar.el, and it may not belong
in menu `Options' either.
