Properties marked as readOnly are shown in POST payload examples

I am using the latest version from I am trying to mark some of my properties in the schema as readOnly:

        get:
            summary: Returns a list with all articles in the system
            responses:
                '200':
                    description: A list of all event series
                    content:
                        application/json:
                            schema:
                                $ref: '#/components/schemas/ArrayOfArticles'
            tags:
                - Backend/Article

                    application/json:
                        schema:

                required: true

        Article:
            type: object
            properties:
                id:
                    type: string
                    readOnly: true
                title:
                    type: string
                content:
                    type: string
                createdAt:
                    type: string
                    readOnly: true
                updatedAt:
                    type: string
                    readOnly: true
            required:
                - id
                - title
                - content
                - createdAt
                - updatedAt
            example:
                id: 1e8b472d03s6ae24457f15a2
                title: My Article 01
                content: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean arcu arcu, finibus sed mattis in, placerat in justo. Proin feugiat semper laoreet.
                updatedAt: 2020-04-06T17:14:37+02:00
                createdAt: 2020-04-06T17:14:37+02:00

This gets rendered as follows:

In the POST request body schema the properties id, updatedAt, createdAt are correctly stripped out.

Unfortunately the sample values are getting displayed in the sample payload of the POST request.

My expectation would be that those properties are getting stripped out from the sample payload in the POST request aswell. Am I missing something?
