Recovery: 94775

This PR fixes #94775

@chrmarti please check if the change makes sense to you, if the input is hidden I simply register a key listener on the list itself to handle navigation with keyboard.

We used to do that in the old quick open world, somewhere here only when quick nav was enabled (= input box hidden):

Looks good thanks!

We'd have to update it if the input box's visibility can change while the QuickInput is already shown, but I understand that this is currently not the case.
