How can we help?

I have

          "success": {
            "type": "boolean",
            "title": "Success",
            "default": false
          },

But I would like the rendered default to be null - even if the type of the argument is success: bool (or, at least with success: bool | None = None (PS: Python)

IIUC, partially of the code responsible is here

swagger-ui/src/core/plugins/samples/fn.js
