Sorting using capabilies.json not working

[krngd2]

According to this article

 "sorting": {
        "default": {   }
    }

Should produce result something like this

It is not working at all,

I tried sorting with

    "sorting": {
        "implicit": {
            "clauses": [
                {
                    "role": "category",
                    "direction": 1
                },
                {
                    "role": "measure",
                    "direction": 2
                }
            ]
        }

This also does not work at all

Am I missing something or is this a bug. Please clarify.

It do works for https://github.com/microsoft/powerbi-visuals-gantt for example
Could you please provide you capabilities.json? Maybe you have some issues with DataViewMapping usage in general
