 Currently, `wp_roles()` only checks whether the global variable
 `$wp_roles` is set before returning it. As global variables can be
 overridden, it should verify that `$wp_roles` is indeed a `WP_Roles`
 object to ensure that `wp_roles()` consistently returns a `WP_Roles`
 instance.

 Refer to `wp_scripts()` and `wp_styles()` for the correct approach.

 See #62562 for another example where the type of a global variable is not
 properly checked.
