Comment:

 This is intentional, as WordPress does not support numeric slugs.
 Appending `-2` transforms the numeric post_id of `123` into a string of
 `123-2`.

 See #5305 for where that was introduced.

 If you want titleless posts to have a different slug, you should be able
 to use the
 [https://developer.wordpress.org/reference/hooks/wp_unique_post_slug/
 wp_unique_post_slug] filter to change numeric-slugs to something else.

 I'm marking this as `invalid` due to the behaviour being intentional, and
 WordPress's inability to support numeric slugs at present.
