You are right. The problem essentially boils down to this:

(let ((minibuffer-completing-file-name t))
 (completing-read "File: " #'completion-file-name-table))

The shadowing works as expected using vertico but not in the default
completion UI. I will try to figure out how exactly that is supposed to
be handled but I think the best place will be the
completion-file-name-table since otherwise every user of the table (or
the completion UI) needs to implement this behavior.
