Non backward compatible change not detected (removed content type result)

[farnulfo]

Hi,

I've used the https://api-diff.io/ to compare two versions of an api.
In the second version a content type return data was deleted but this non backward compatible change was not detected by https://api-diff.io/ : "No API structure changes detected"

Here the two files I used
Simple-API-V1.yaml.txt
Simple-API-V2.yaml.txt

This breaking change is detected by https://github.com/OpenAPITools/openapi-diff :

`C:\openapi-diff-master\cli>java -jar target\openapi-diff-cli-2.1.0-SNAPSHOT-all.jar Simple-API-V1.yaml Simple-API-V2.yaml

== API CHANGE LOG ==

                            Simple API

-- What's Changed --

• GET /users/{userId}
  Return Type:
  • Changed 200 OK
    Media types:
    • Deleted application/xml

---

-- Result --

             API changes broke backward compatibility
