Comment (by flixos90):

 The problem here is that the `WP_Roles` class does not support passing a
 site ID, so it will always retrieve the roles registered on the current
 site. A possible solution for it could be to add a `switch_to_blog()` (and
 `restore_current_blog()`) before the `wp_roles()` call in `WP_User`.

 This switch must only happen if we're on a multisite setup and if the
 `$cap_key` property is different from the one of the current site (and
 then we'd need to extract the site ID out of it, or alternatively find a
 suitable way to directly pass the site ID to the `get_role_caps()`
 method).
