Sibling values alongside a $ref are ignored by swagger editor 2.0

[sdghchj]

Describe the bug
Sibling values alongside a $ref are ignored by swagger editor 2.0.

If we want to add properties to $ref, It is suggested to wrap $ref into allOf.

  types.Person:
    type: object
    properties:
      class:
        desription: aaa   
        $ref: '#/definitions/types.Class'

as above, description will be ignored.

Expected behavior

  types.Person:
    type: object
    properties:
      class:
        desription: aaa
        allOf   
          - $ref: '#/definitions/types.Class'
