Product slider with dynamic product group not loading associations

After upgrading to version 6.6.7.0, the product slider using dynamic product groups is no longer loading associations and manufacturer information.

Previously, I had overridden the class by extending ProductSliderCmsElementResolver to include the following line in my code:

$criteria->addAssociation('properties.group')->getAssociation('properties');

This approach was working correctly, but since the update, it has stopped functioning, and I am unable to resolve the issue.

I would appreciate any guidance on how to restore this functionality.
