operation level server override option always appears for OAS 3.1 specification

This option seem to appear for OAS 3.1 documents when servers are not specified globally. Although servers are not specified on operation level either, swagger-ui defaults to '/' and always displays the override.

Hi @aharin,

It's related to the fact that OpenAPI 3.1.0 resolution is facilitated by ApiDOM which utilizes (currently) full duplication and normalization algorithms. I can imagine this is not warranted for the SwaggerUI usecase. SO we'll review the normalization for OpenAPI 3.1.0 in foreseeable future.

@aharin my team just saw this when navigating directly to the url of an expanded endpoint. It was preventing us from sending requests via the doc. A workaround that worked for me: navigate to the root (delete stuff after #) and hard refresh your browser, the dropdown should be absent after expanding the endpoint and clicking “Try it out”
