reference name is not displayed in OpenApi 3.1.0 renderer

Q&A

• OS: macOS
• Browser: chrome
• Version: 121.0.6167.139
• Method of installation: dist, cloud
• Swagger-UI version: any recent version, (checked from 5.2 to 5.10.3)
• Swagger/OpenAPI version: 3.1.0

A simple example Swagger/OpenAPI definition:

openapi: 3.0.3
info:
  title: Example
  version: 0.0.1
paths:
  /api/v1/example:
    get:
      operationId: example
      responses:
        '200':
          description: ''
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Node'
components:
  schemas:
    Node:
      required:
      - id
      type: object
      properties:
        id:
          $ref: '#/components/schemas/NodeId'
        name:
          type: string
        parentId:
          $ref: '#/components/schemas/NodeId'
    NodeId:
      type: integer
      description: Internal ID of a Node
      format: int32

Describe the bug you're encountering

When switching openapi: 3.0.3 to 3.1.0 renderer no more displays references with their names.

Expected behavior

Referenced types are shown with their name so it's easy to see reused components

To reproduce...

Use a provided example and compare results between 3.0.3 and 3.1.0

Actual behavior

Referenced types are inlined without name (e.g. NodeId in provided simple example) - hard to see common components when using complex schemas.

Screenshots

Load the provided YAML example in the Swagger UI renderer and compare the displayed schemas for OpenAPI 3.0.3 and 3.1.0, focusing on the NodeId references. The work is done when referenced types retain their component names in the 3.1.0 renderer as they do in 3.0.3.
