redoc: Incorrectly parsed reference fails to resolve

I’m using the latest stable CDN-hosted ReDoc version on the Swagger 2.0 and JSON Schema documents at the end of this post. When loading this in ReDoc, it fails with the following error: ERROR Error: Uncaught (in promise): SyntaxError: Error resolving $ref pointer "http://127.0.0.1:5000/about/json/schema#/definitions/schema". Token "schema" does not exist.. As you can see in the documents below, this subschema does indeed not exist, but I don’t know why ReDoc tries to load it. I’m hoping someone here might. The same JSON schema is also parsed and resolved by a Python library, which works well, so at this point like the error is caused by something on ReDoc’s side.

Please let me know if I can provide more information. Once https://github.com/Rebilly/ReDoc/issues/388 has been addressed, I can hopefully help debug this error myself locally 😃
