Specifying shape, height, width, x and y properties of navigators in powerbi theme file

[s_farooq]

I am looking to specify the shape, height, width, x and y properties of navigators in powerbi theme file.

below is a snipped from the theme:

    "pageNavigator": {
      "*": {
        "shape": [
          {
            "tileShape": "tabCutCorner",
            "tabCutCornerSnipSizeTopRight": 25
          }
        ],
        "pages": [
          {
            "showHiddenPages": true,
            "showByDefault": false
          }
        ],
        "layout": [
          {
            "orientation": 2,
            "cellPadding": 0
          }
        ],
        "general": [
          {
            "height": 30,
            "width": 570,
            "x": 105,
            "y": 30
          }
        ],
        "padding": [
          {
            "bottom": 0,
            "left": 0,
            "right": 0,
            "top": 0
          }
        ]
      }
    },

But it doesnt seem to have any effect. Whenever I create a new navigator, it is created the default size.
