bundle does not produce schemas + circular pointers in preview-docs

Describe the bug
Hello again! After the feedback I got in #543, I've updated our spec to successfully bundle, however I noticed that bundle isn't fully rendering the schemas. Instead, they show up as refs:

                  - type: object
                    required:

                        items:

      $ref: '#/components/parameters/createdAfter'
  schemas:
    cursor:
      $ref: '#/components/schemas/cursor'
    syncToken:
      $ref: '#/components/schemas/syncToken'
    BaseResponse:
      $ref: '#/components/schemas/BaseResponse'
    PaginatedResponse:
      $ref: '#/components/schemas/PaginatedResponse'
    InterviewSchedule:
      $ref: '#/components/schemas/InterviewSchedule'

Initially, I thought maybe bundle without --dereferenced is only meant to have refs everywhere, like this. So, I tried to preview-docs, and the page fails to get past the loading spinner. The following is printed in the console:

To Reproduce
Steps to reproduce the behavior:

1. Given the attached multi-file openapi setup
2. Run openapi bundle openapi.yml or openapi preview-docs openapi.yml

Expected behavior
Bundles the spec with schemas + preview-docs renders the API documentation

Additional context
I might be misinterpreting how bundle works vs bundle --dereferenced. Happy to file a ticket if these issues are unrelated!

Yes, this is a known issue and we're working on it.

As a workaround you have to remove the schemas section from your root file. All used schemas will be added there automatically.

Please track it here: #290
