Do other menus work for you?  What do you see when clicking
C-<down-mouse-1> bound to mouse-buffer-menu, or S-<down-mouse-1>
bound to mouse-appearance-menu, or C-<down-mouse-3> bound to
mouse-menu-bar-map, etc.

Does this patch work for you?  If yes, then we could create
context-menu-mode-map active for context-menu-mode
and add these keybindings to it.
