wp_get_current_user() doesn't return roles and capabilities on a multisite

wp_get_current_user() doesn't return roles and capabilities on a multisite even when you're logged in as a super admin. This is causing ​https://github.com/woocommerce/woocommerce-admin/issues/7004

How to test:

1. Create a new multisite
2. Make sure to turn on

define( 'WP_DEBUG', true
define( 'WP_DEBUG_LOG', true )

3. Add a new site. Use a different email address than the admin email.
4. Use this plugin (copy from this ​https://gist.github.com/moon0326/34551bd7cedbd633e7d510ba9fca35d9) to print return value of wp_get_current_user().
5. Open terminal and cd to :your-wordpress-dir/wp-content/ and start tailing debug.log
6. Visit the new site. Notice that the WP_User object has no roles.
7. Go back to the original site. Notice that the WP_User object has roles now.

@moon0326 Does the Super Admin user have a role on the new site that you added? If not, this is expected behaviour. A Super Admin can perform any action on any site on the network, but they won't have a role or any capabilities on the site unless they're added to that site.

Thank you for the clarification. That makes sense.

Thanks for the update! In that case I'll close this off.
