Impacted component(s)

Menu

Expected behavior

Similar to how sp-menu supports navigating across with the help of keyboard arrow keys, it should also support Numpad arrow. Numpad Enter key also should work similar to the main Enter key.

Actual behavior

Numpad keys are not handled at all.

I can see the issue in https://github.com/adobe/spectrum-web-components/blob/main/packages/menu/src/Menu.ts, where instead of using event.code if event.key is used, this would be fixed.
