I can reliably reproduce the bug, but for me it's a sympton of broader
buggy behavior with menus in the Lucid build, which I've observed since
I started regularly building with the Lucid toolkit some months ago
(after not doing so for many years previously, so I don't know how old
this behavior is).

So while the items of a context menu (but not those of a submenu) can be
scrolled with the mouse, context menus are completely unresponsive to
keyboard events.  In contrast, with menus from the menu bar (whether
open via mouse click for with the F10 key binding), I can both navigate
and select (also in submenus) with the keyboard but other than opening
and closing, the menu bar menus are completely unresponsive to the
mouse.

Here's my current build info:
