At line 462 of ResolveFully class, extensions of only source schemas are being added to target schema. Shouldn’t it copy extensions of resolved schemas as well, similar to the way properties and required of resolved schemas are handled? https://github.com/swagger-api/swagger-parser/blob/2db8c628cbbfdd8afb972965698e011c93747b15/modules/swagger-parser-v3/src/main/java/io/swagger/v3/parser/util/ResolverFully.java#L462

can you add sample files or possibly a pr with failing test case?.

Here's a simple case to reproduce

openapi: "3.0.2"
info:
  title: "Extension not inherited"
  
components:
  schemas:    
    ResponseModel:
      x-extension-ref: 1
      type: object
      required:
        - data
      properties:
        data:
          type: "string" 
          
paths:
  /test/extensions/not/inherited:
    get:
      responses:
        200:
          content:
            application/json:
              schema:
                allOf:
                - $ref: "#/components/schemas/ResponseModel"
                - type: "object"
                  required:
                  - "data"
                  properties: 
                    data2:
                      type: "string"
