Investigating further, I find that if I launch a lucid "emacs-28" via

src/temacs -Q

and evaluate (menu-bar-mode -1) then the popup menu, formed from <f10>,
does indeed allow navigation from the arrow keys (as well as the
mouse). Only launching "emacs-28" from the following

1. src/emacs -Q
2. src/bootstrap-emacs -Q
3. src/emacs-28.0.50.1 -Q

fails to allow the popup menu-bar to be navigable from the arrow keys.


I hope this helps.

Best wishes,

Colin Baxter.
