Content & configuration

In case of deep inheritance ordering of models might lead to incorrect behavior

Example 1. Order: BaseObject, ExtentionObject1, ExtentionObject2, ExtentionObject3
Example Swagger/OpenAPI definition:

openapi: 3.0.0
info:
  version: '1'
  title: Test API

paths:
  '/objects':
    get:
      responses:
        200:
          description: result
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/ExtentionObject3'

components:
  schemas:
    BaseObject:
      type: object
      allOf:
        - type: object
          properties:
            baseObjectProp1:
              type: string
            baseObjectProp2:
              type: string

    ExtentionObject1:
      allOf:
        - $ref: '#/components/schemas/BaseObject'

    ExtentionObject2:
      type: object
      allOf:
        - $ref: '#/components/schemas/ExtentionObject1'
        - type: object
          properties:
            extObject2Prop:
              type: string

    ExtentionObject3:
      type: object
      allOf:
        - $ref: '#/components/schemas/ExtentionObject2'
        - type: object
          properties:
            extObject3Prop:
              type: string

Example 2 with reversed order. Order: ExtentionObject3, ExtentionObject2, ExtentionObject1, BaseObject
Example Swagger/OpenAPI definition:

openapi: 3.0.0
info:
  version: '1'
  title: Test API

paths:
  '/objects':
    get:
      responses:
        200:
          description: result
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/ExtentionObject3'

components:
  schemas:
    ExtentionObject3:
      type: object
      allOf:
        - $ref: '#/components/schemas/ExtentionObject2'
        - type: object
          properties:
            extObject3Prop:
              type: string
              
    ExtentionObject2:
      type: object
      allOf:
        - $ref: '#/components/schemas/ExtentionObject1'
        - type: object
          properties:
            extObject2Prop:
              type: string

    ExtentionObject1:
      allOf:
        - $ref: '#/components/schemas/BaseObject'
              
    BaseObject:
      type: object
      allOf:
        - type: object
          properties:
            baseObjectProp1:
              type: string
            baseObjectProp2:
              type: string

Describe the bug you're encountering

In Example 1 in Models section ExtentionObject3 only have 2 properties. In Example 2 it has 4 properties as expected.

To reproduce...

Paste examples, force refresh page (sometimes it works when page is not force refreshed)

Expected behavior

In both cases ExtentionObject3 should have 4 properties
