On multisite, when checking if a user has a certain capability WordPress makes an additional check to see if the user is a super admin. The `is_super_admin()` function contained a call to `wp_get_current_user()` so as the global current user object could be used if it matched the queried user id. This would cause an infinite loop if a hook attached to the `determine_current_user` filter was itself making a permission check. For example when limiting who can use the Application Passwords feature based on their capabilities. Since [50790] the `WP_User` instance for the current user is shared between `wp_get_current_user()` and `get_userdata()`. This means we can remove the `wp_get_current_user` call from `is_super_admin()` while still retaining the same behavior. Props chrisvanpatten, peterwilsoncc.
