multipart/form-data with application/json field doesn't work

[tamis-laan]

Given a route specification with the following request body:

   requestBody:
     required: true
     content:
       multipart/form-data:
         schema:
           type: object`
           required:
             - image
             - json
           properties:
             image:
               type: string
               format: binary
             json:
               $ref: '#/components/schemas/MySchema'
         encoding:
           image:
             contentType: image/*
           json:
             contentType: application/json

I get the following error:

request.body.json should be object {
  "errors":[{
    "errorCode":"type.openapi.validation",
    "message":"should be object",
    "path":".body.json"
  }],
  "name":"Bad Request",
  "status":400
}
