Thanks for the report.  However, POSIX require -d to treat directories
as files rather than directories, and says that mixing -d and -R is
unspecified:

In GNU, we take this to mean that -d always overrides -R, because
recursion makes sense only if you treat a directory as a directory, but
-d says to treat it as a file instead.

If you need to mix recursion with listing of directories, consider using
find(1), as in:

find . -type d

or with specific ls options:

find . -type d -exec ls -ld {} +

As such, I'm closing this as not a bug; but you are free to still add
comments or questions to this conversation.
