Broken mutual recursion

[tiopid]

Describe the bug
After this fix -

fix: rewrite recursive checks

i got the problem with mutual recursion object, because here https://github.com/Redocly/redoc/blob/master/src/services/OpenAPIParser.ts#L12
only the previous $ref is checked

components:
  schemas:
    A:
      type: array
      items:
          $ref: '#/components/schemas/B'
    B:
      allOf:
        - $ref: '#/components/schemas/C'
        - $ref: '#/components/schemas/D'
    C:
      type: object
      required:
        - value
      properties:
        value:
          $ref: '#/components/schemas/A'
    D:
      type: object

Hi @tiopid, thanks for your issue.
I tried to check your case using definition:

openapi: 3.0.0
info:
  title: False positive recursion
  version: '3.0'
paths:
  /documents:
    get:
      summary: Example
      responses:
        '200':
          description: OK
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/A"
components:
  schemas:
    A:
      type: array
      items:
          $ref: '#/components/schemas/B'
    B:
      allOf:
        - $ref: '#/components/schemas/C'
        - $ref: '#/components/schemas/D'
    C:
      type: object
      required:
        - value
      properties:
        value:
          $ref: '#/components/schemas/A'
    D:
      type: object
                                                

But on commits:
before changes 992099
on changes 2970f9
rc-74
rc-75

I had the same result.

Please provide more clear steps to reproduce and expected behavior.

Thanks

sorry, this is correct example
somesing like this compiled by speccy from different files

openapi: 3.0.1
info:
  title: False positive recursion
  version: '3.0'
paths:
  /documents:
    get:
      summary: Example
      responses:
        '200':
          description: OK
          content:
            application/json:
              schema:
                allOf:
                  - type: object

                        properties:
                          A:

                                    - title: tableLookup
                                      type: object
                                      properties:
                                        fallback:
                                          type: array
                                          default: []
                                          items:
                                            $ref: "#/paths/~1documents/get/responses/200/content/application~1json/schema/allOf/0/properties/%40relations/properties/A/properties/B"
                  - type: object
                    required:
                      - "@relations"
                    properties:
                      "@relations":
                        type: object
                        properties:
                          A:
                            $ref: "#/paths/~1documents/get/responses/200/content/application~1json/schema/allOf/0/properties/%40relations/properties/A"
      

I noticed that the error occurs because both objects in allOf the properties are called A, and B items with oneOf
