bug#49888: 28.0.50; fido-mode not sorting by recency

[Manuel Uberti]

In 'emacs -Q', this is what I did:

- M-x savehist-mode RET
- M-x fido-mode RET
- M-x icomplete-vertical-mode RET
- M-x emacs-init-time
- C-x p p, pick a Git-versioned directory RET
- f, pick the fourth candidate, C-x k RET
- M-x now shows pr-ps-file-preview on top
- C-x p p, pick the only available project
- C-x p f does not offer the previously selected candidate

Is it possible to make fido-mode sort the candidates by recency?
