Referenced schemas lose default property

[onavratil-monetplus]

Describe the bug

Redocly often fails to display default values of properties, although they are defined in accordance with standard.

To Reproduce
Steps to reproduce the behavior:

Given this api and separate model:

openapi: 3.1.0
tags:
  - name: test
info:
  title: Bundle Sample
  version: '0.1.0'
  description: |
    Sample API
  contact:
    name: Ondřej Navrátil
    email: [email protected]
servers:
  - url: '127.0.0.1'
    description: localhost
paths:
  /test-endpoint:
    post:
      summary: Sample endpoint
      operationId: post-something
      description: |-
        xxx.
      requestBody:
        content:
          application/json:
            schema:
                type: object
                properties:
                  testProperty:
                    $ref: some-model.yaml
                  testProperty2:
                    title: Test Property 2
                    description: |
                      Whatever2.
                    type: string
                    enum:
                      - ABCD
                      - EFGH
                    default: ABCD
      responses:
        '200':
          description: OK
          content:
            application/json:
              schema:
                type: object
                properties:
                  testProperty:
                    $ref: some-model.yaml
      tags:
        - test

Model:

title: Test Property
description: |
  Whatever.
type: string
enum:
  - ABCD
  - EFGH
default: ABCD

Running the following

$ redocly build-docs sample-api.yaml 

...redocly fails to display defaults in the referenced schemas. Note that the same model is displayed correctly when explicitly dereferenced.

Expected behavior

Defaults are displayed even in referenced models.
