using plugin with goo.gl shortcute

Hello,

I am using goo.gl short urls(with googl plugin)
I changed some code facebook plugin
it is ok. Works.
But normally when i share manually a goo.gl link. On facebook Under title url is normal web site url (not goo.gl examp. domain.com)

But When i share with facebook plugin. Under title url shown goo.gl

How can i fix it?

Thanks.

I changed;
facebook/admin/social-publisher/social-publisher.php

OLD code
$link = apply_filters( ‘facebook_rel_canonical’, get_permalink( $post_id ) );
New Code
$link = apply_filters( ‘facebook_rel_canonical’, wp_get_shortlink( $post_id ) );
