Yes we already mention that, but such behavior is not the default, wo
when we say zsh behavior, that's not usually what a zsh user expects.

are not visible, it does not make sense to enable arrow navigation.

No, this only happens with the minibuffer navigation... with normal
navigation in completions there is not issue for me.
