Ah I wasn't clear, it's also an issue with yank-menu.  Probably
basically the same bug?  Recipe:

1. emacs -Q
2. M-x context-menu-mode RET

4. C-h k and right click, then "Paste from Kill Menu", then "(any string)".
5. Observe the help buffer claims the key sequence was:
<down-mouse-3> <paste-from-menu> C-a
