Comment:

 Thanks for the report.

 I've confirmed the issue. The problem is not that `'roles'` is *empty* per
 se, it's that roles/caps are being populated from the wrong site in some
 cases (and in your situation, the user doesn't have any role at all on the
 current site). In [15566], `WP_User_Query` was modified to ensure that
 caps are fetched from the proper 'blog_id'; in [22248], `WP_User_Query`
 was modified to return `WP_User` objects when 'fields=all', but the
 blog_id fix from [15566] was not included in the latter changeset.
