I think "Select Buffer" is wrong simply because it is different from
"Buffers".  I mean, what is the point of showing one text (Buffers)
when the menu is not selected, and another text (Select Buffer) when
it is?  I've not seen such a thing before anywhere, and I don't see
what sense it does make.  (the GUI "Buffer" menu of course does not
exhibits such a strange behavior).

That's the current behavior, yes.

Well, the current design is surely simpler, but IMO it is definitely
not the best one.  When I am navigating through the top level menus I
obviously expect every header to stay where it was before it was
selected.  When I type C-f to reach the "Help" menu (from the
Lisp-Interaction menu) and see that weird effect... mmm it clearly
feels counter intuitive to me.

?? What sense does it make to show that residual "elp" string at the
right of the "Help" header?  It is not the end of the world, but I
really don't think it is TRT either.

The mouse doesn't work here (on a TTY session).

I hope you to reconsider that, because IMHO it is a misfeature.

That's a pity.  It would be nice to have those drop-down text menus
also on GUI sessions.  Then consider this point a feature request then
(who knows, perhaps some day it might be implemented).

See above, but you are the maintainer, so you decide.
