declaring product as select2 does not work

Hi, it appears that declaring product or department as a select2 field does not work in the ticket submit form:

function wpas_make_product_required( $custom_fields ) {
        if ( isset( $custom_fields['product'] ) ) {
                $custom_fields['product']['args']['required'] = true;
                $custom_fields['product']['args']['select2'] = true;
        }
        return $custom_fields;
}

To make it work you have to either declare first a custom field as select2, or use the following hack:

add_action( 'wp_enqueue_scripts', array( Awesome_Support::instance()->custom_fields, 'enqueue_select2_assets' ) );
