Parser ignore the description if it's a $ref

As said in the title, latest stable release ignores the description if it's a $ref.
It looks like a regression to me because it was working properly a few versions back (can't be sure when, I found at using a code generator).

[main] INFO  o.o.codegen.DefaultCodegen - debugging Cateogry: class Schema {
    type: null
    format: null
    $ref: #/components/schemas/Category
    description: null
    title: null
    multipleOf: null
    maximum: null
    exclusiveMaximum: null
    minimum: null
    exclusiveMinimum: null
    maxLength: null
    minLength: null
    pattern: null
    maxItems: null
    minItems: null
    uniqueItems: null
    maxProperties: null
    minProperties: null
    required: null
    not: null
    properties: null
    additionalProperties: null
    nullable: null
    readOnly: null
    writeOnly: null
    example: null
    externalDocs: null
    deprecated: null
    discriminator: null
    xml: null
}

description is null even though I put down something as follows:

       category:
         $ref: '#/definitions/Category'
        description: "description testing"

Start with the YAML example where a schema has both $ref and description, then trace how the parser represents and processes that schema. Compare the current result with an earlier release if available, and verify that the description is preserved when parsing the example.
