Describe the bug you're encountering

Specification says A unique parameter is defined by a combination of a name and location.

I defined bar parameter in path location at PathItem and I defined parameter with same name bar, in header location at Operation.

To reproduce...

Steps to reproduce the behavior:

1. Go to app.swaggerhub.com.
2. Register and create new API.
3. Paste OpenAPI yaml from the example (above).
4. See error in POST method: One parameter bar in header location displayed. No bar in path location parameter.

Expected behavior

Expected two parameters in POST method: bar in path location and foo in header location.
