What happened?

I'm having a problem with the Joomla 6.1.2 update and Gantry/Helium or Gantry/Hydrogen. Since this update, the menus managed by Gantry have disappeared.

Additional Comments

I found the origin of the problem.

The file \components\com_content\src\Model\ArticleModel.php was modified between Joomla 6.1.1 and 6.1.12.

After the statement $data->params = clone $this->getState('params'); on line 230, the statement $data->params->merge($registry); is missing, and this is what causes the anomaly.
