Alas, after the last commit c1ea52f4ad in the feature/completions-customs branch
this is not possible anymore.

Before this commit we were able to let-bind
`cursor-face-highlight-mode' in the new command:

```
(defun minibuffer-previous-completion (&optional n)
  "Run `previous-completion' from the minibuffer in its completions window."
  (interactive "p")
  (with-minibuffer-completions-window
    (let ((cursor-face-highlight-mode t))
      (previous-completion n))))
```

because 'redisplay--update-cursor-face-highlight' was always
presented in `pre-redisplay-functions', and the mode was checked with

  (when cursor-face-highlight-mode

But now the hook is added only when mode is enabled.
