AllOf + $ref + Array + $ref is somehow skipped

Swagger2Markup version: 1.3.0 (also happens in 1.2.0)

Problem description: When using the following response setup in my swagger YAML:

      responses:
        '200':
          description: Success
          schema:
            allOf:
            - "$ref": "#/definitions/APIResponse"
            - type: object
              properties:
                data:
                  type: array
                  items:
                    "$ref": "#/definitions/Folder"

The adoc output simply generates a "No Content" spec:

==== Responses

[options="header", cols=".^2,.^14,.^4"]
|===
|HTTP Code|Description|Schema
|**200**|Success|No Content
|**401**|Unauthorized access. Please log in first.|No Content
|**403**|Forbidden. You don't have access to this particular API resource.|No Content
|===
