Detailed Description

I have simple swagger 2 doc: (click to reveal spoiler)

swagger: '2.0'

      operationId: doSomething
      consumes:
        - application/x-www-form-urlencoded
        - multipart/form-data
      produces:
        - application/json
      parameters:
        - name: client_id
          in: formData
          description: Client identifier (serviceName)
          required: true
          type: string
        - name: client_secret
          in: formData
          description: Сlient secret (api-key)
          required: true
          type: string
        - name: access_type
          in: formData
          description: Access scheme
          required: true
          type: string
        - name: scope
          in: formData
          description: scope
          required: false
          type: string
        - name: username
          in: formData
          description: User's login
          required: false
          type: string
      responses:
        '200':
          description: OK
          schema:
            $ref: '#/definitions/AccessTokenResponse'
        '500':
          description: ServerError
          schema:
            type: string
definitions:
  AccessTokenResponse:
    required:
      - access_token
    type: object
    properties:
      access_token:
        description: Access token
        type: string
      expires_in:
        description: Lifetime of token
        type: integer
      token_type:
        description: Token type
        type: string
        default: Bearer

with 1 endpoint which consumes 2 content-types: application/x-www-form-urlencoded and multipart/form-data.
After conversion to openAPI v3.0.x application/x-www-form-urlencoded content-type is missing.

I also converted my swagger doc at https://mermade.org.uk/openapi-converter and saw same result

I think this is a bug because conversion to openAPI v3.0.x at https://editor.swagger.io/ doesn't erase application/x-www-form-urlencoded content-type
