I'm documenting a list of APIs using OpenAPI 3.0 and a separate YAML file for each API.

All APIs use the same target server, so currently I have the following in each API definition:
`

  servers:
      - url: www.abc.com   
        description: "Production Server" 

`
But I don't want to repeat the servers in all API definitions. Instead, I would like to reference the servers from a single file, like so:

`

    //sample.yaml
     ...
    servers:
    $ref: 'index.yaml#/servers'

`

But Swagger UI shows the "Could not render this component" error.

Is it possible to $ref the servers in OpenAPI 3.0 definitions?
