additionalProperties attribute in an object with allOf

[rifkiKargo]

Hi, i have a schema where it looks like this:

UpdateOrderDetail:
      type: object
      additionalProperties: false # Prohibits fields not explicitly listed
      allOf:
        - $ref: "#/components/schemas/BasicOrderDetail"
        - type: object
          properties:
            handlingUnitInfo:
              $ref: '#/components/schemas/BasicHandlingUnitDetail'

I have additionalProperties attribute in the object, where it also has allOf. The current code seems to not care about any attributes in an object if it has allOf, hence the additionalProperties does not seem to work as of now for the above schema. Is there any particular reason on why it works that way? or maybe my schema formatting is actually not common?

Would be great if someone can enlighten me on this one as im trying to start using the lib :D
