Indeed that's a bug: the Lisp-Interaction should also disappear.
It seems to be a bug in the code that builds the menu-bar from the
active keymaps.

Even if erasing all the items is the intended behavior (I think
disabling all the items is less surprising at least for the tool-bar),
its timing is inconsistent.  For example, if you replace Step 2 above
with (read-key) C-j, then menu-bar and tool-bar items don't disappear
immediately, but if you move the mouse pointer over a tool-bar item
and wait for a tooltip to be shown, then they will disappear.

In Emacs 24, I get (sort of) the opposite result.  When I `M-:', the
Lisp-Interaction menu disappears, and most of the tool bar items get
greyed out.

So I guess this has been fixed?

I confirm that in Emacs 25 it looks OK. When I type M-: the
lisp-interaction menu is replaced with a Minibuf one, which makes sense
to me.
