I don't know what I did wrong but this does nothing:

  (global-set-key [down-mouse-3] [context-menu])
  (global-set-key [context-menu]
    `(menu-item ,(purecopy "Context Menu") ignore
      :filter (lambda (_) (mouse-context-menu-map))))

whereas this works fine:

  (global-set-key [down-mouse-3]
    `(menu-item ,(purecopy "Context Menu") ignore
      :filter (lambda (_) (mouse-context-menu-map))))

A minor mode will also need to remove this binding

  (define-key key-translation-map [mouse-3]
    #'mouse--click-3-maybe-context-menu)

when `mouse-3-down-context-menu` is t, and to unbind
[mouse-3] from 'mouse-save-then-kill' because sometimes
'mouse-save-then-kill' still gets called, I haven't investigated why.
