So /cf is a symlink in your setup?

The reason for this behaviour is a patch from 2011 which attempted to
make this command work on the "." and ".." directories:

  (let ((tem (dired-get-filename t t)))
    (if tem
	(browse-url-of-file (expand-file-name tem))

So we want to call with (browse-url-of-file "/") instead of
(browse-url-of-file "/tmp/.."), for instance, and use expand-file-name
to achieve that.  However, that function also resolves any symlinks...

This function just needs to do the ../. thing.  Does Emacs have a
function that just does the right thing the ".." and "/" and does
absolutely nothing else?
