Yes.  TTY menus behave like the no-toolkit build of Emacs behaves,
because they share some of the code and the general design.

You don't like it because you are used to how the various GUI toolkits
behave: they leave the menu displayed when you release the mouse
button.  But Emacs has always produced both kinds of behaviors,
depending on the toolkit (or lack thereof).  The reason for popping
down a menu on mouse release is that otherwise one needs a separate
event loop (which toolkits have and TTY mouse doesn't).

??? Of course, it possible: type F10, and then use arrow keys to
navigate and RET to select.
