ls: --hyperlink -R omits parent dir when displaying child dir

[cakebaker]

While reviewing https://github.com/uutils/coreutils/pull/6144 I discovered the following issue:

$ mkdir -p dir/subdir
$ cargo run ls --hyperlink -R dir
dir:
subdir

subdir:   <- parent dir is not shown
$ ls --hyperlink -R dir
dir:
subdir

dir/subdir:

Without --hyperlink, the correct output is shown.
