with emacs -Q

1) 
M-x -> fido-mode
C-x C-f -> type "$HOME" -> enter opens dired buffer in $HOME directory
instead of continuing find-file $HOME to select a file to open

2)
similar thing happens if:
M-x -> fido-mode
C-x C-f -> type "$HOME/.emacs.d" -> enter opens dired buffer in $HOME/emacs.d directory
instead of continuing find-file $HOME/emacs.d to select a file to open

in pure icomplete-mode find-file seems to work as expected after typing "$HOME/" 
-> descent into directories via C-M-i?

ido-mode will not match environment variables but when typing

M-x -> ido-mode
C-x C-f -> type "$HOME/" -> ido expands $HOME to the actuall path and
find-file continues as expected

ido.el has

(defun ido-complete ()
  "Try and complete the current pattern amongst the file names."
  (interactive)
  (let (res)
    (cond
     (ido-incomplete-regexp
      ;; Do nothing
      )
     ((and (memq ido-cur-item '(file dir))
	   (string-match "[$]" ido-text))
      (let ((evar (substitute-in-file-name (concat ido-current-directory ido-text))))
	(if (not (file-exists-p (file-name-directory evar)))
	    (message "Expansion generates non-existing directory name")
	  (if (file-directory-p evar)
	      (ido-set-current-directory evar)
	    (let ((d (or (file-name-directory evar) "/"))
		  (f (file-name-nondirectory evar)))
	      (when (file-directory-p d)
		  (ido-set-current-directory d)
		  (setq ido-text-init f))))
	  (setq ido-exit 'refresh)
	  (exit-minibuffer))))

This was tested in emacs 28 but also 27

Thanks, I reproduced this and will try to fix it.  Doesn't seem very
hard, but we'll see.

I pushed a commit to master that should fix it. It's
45d711a356b4c5e75d0b6e4391313ca34f57b4bb, a very simple patch:

Closing this bug, but I'll reopen if it ends up not doing what you
wanted.

Thank you very much for looking at this! 

Now, if I type $HOM I get candidate $HOME, then I have to M-Tab to insert the candidate and type "/" to continue find-file in the directory, and then everything works as expected. This makes it now definitely usable for me! 

It might still be a bit confusing that in case of an environment variable which value is a directory, Enter does open dired instead of transversing into the directory with find-file (typing $HOM followed by Enter opens dired in home). But I don't know if changing this would be better or worse than the current behaviour after your fix - or possible at all.

Simon

May be possible. Is that what Ido does? I'll try in a couple of days, ping
me here if I forget.

great, will do!

off topic:

would also be nice to have some simple helper functions to go to the first and last match in case of fido-vertical-mode, something along the lines of

(defun icomplete-vertical-last-completions ()
  "Go to last completions entry..."
  (interactive)
  (let* ((beg (icomplete--field-beg))
         (end (icomplete--field-end))
         (comps (completion-all-sorted-completions beg end))
         (last (last comps)))
    (while (consp (cdr comps))
      (push (pop comps) icomplete--scrolled-past)
      (setq icomplete--scrolled-completions comps)
      (completion--cache-all-sorted-completions beg end comps))))

(defun icomplete-vertical-first-completions ()
  "Go to first completions entry..."
  (interactive)
  (let* ((beg (icomplete--field-beg))
         (end (icomplete--field-end))
         (comps (completion-all-sorted-completions beg end))
	 last-but-one)
    (while icomplete--scrolled-past
           (push (pop icomplete--scrolled-past) comps)
           (setq icomplete--scrolled-completions comps))
    (completion--cache-all-sorted-completions beg end comps)))
