I'm quite sure it's how the mouse support behaves, and has nothing to
do with what Juri did.  You should see the same behavior in any menu
on that display.

It works for me as you expect on the w32 console.

I don't see how this can be worked around in a hook, because TTY menus
are implemented entirely in C.

We could do something similar to what we do when the user presses F10
on a TTY frame.

Why pointless? menus work on TTY frames without a mouse just fine, you
can move and select using the keyboard.
