REST CRUD Controller incorrectly calls apply_filters

In WooCommerce v5.4.1 the class-wc-rest-crud-controller.php class calls the “rest_{$this->post_type}_collection_params” filter incorrectly:

/**
 * Filter collection parameters for the posts controller.
 *
 * The dynamic part of the filter <code>$this->post_type</code> refers to the post
 * type slug for the controller.
 *
 * This filter registers the collection parameter, but does not map the
 * collection parameter to an internal WP_Query parameter. Use the
 * 'rest_{$this->post_type}_query' filter to set WP_Query parameters.
 *
 * @param array        $query_params JSON Schema-formatted collection parameters.
 * @param WP_Post_Type $post_type    Post type object.
 */
return apply_filters( "rest_{$this->post_type}_collection_params", $params, $this->post_type );

The PHPDoc states the $post_type variable is meant to be of type WP_Post_Type, however this call provides the parameter as a string.

When WP calls the same filter it provides a WP_Post_Type object.
