Description

with a manual accept header as a header param, the generated code overrides passed in params with the inferred ones.

/endpoint:
  get:
    parameters:
      name: Accept
      required: false
      in: header
      description: |
          Media type that is acceptable by the client to control the content negotiation for the response.
      schema:
        type: string
        example: "application/json"
    responses:
      '200':
        content:
            application/octet-stream:
              schema:
                type: object
            application/json:
              schema:
                type: object

generates:

        accept?.apply { localVariableHeaders["Accept"] = this.toString() }
        localVariableHeaders["Accept"] = "application/octet-stream, application/json"

which makes the accept parameter ineffective.
