Polygon of world map with a hole (google maps)

Question

I am trying to draw a rectangle polygon with a hole. My problem is that I cannot create a polygon that covers the whole world. The polygon is inverted so that only a single line is selected instead of the whole world.

Below an example of the maximum selection I am able to make. For example if I try to alter 0 (in the line new google.maps.LatLng(-85.1054596961173,0)) to any other value the inverted selection is used.

Maybe I am missing something obvious here, but I can't seem to get it working.

function initialize() {
  var mapOptions = {
    zoom: 1,
    center: new google.maps.LatLng(24.886436490787712, -70.2685546875),
    mapTypeId: google.maps.MapTypeId.TERRAIN
  };


  var map = new google.maps.Map(document.getElementById('map-canvas'),
      mapOptions);

  var worldCoords = [
    new google.maps.LatLng(-85.1054596961173, -180),
    new google.maps.LatLng(85.1054596961173, 180),
    new google.maps.LatLng(85.1054596961173, 180),
   new google.maps.LatLng(-85.1054596961173,0)

  ];

  var EuropeCoords = [
              new google.maps.LatLng(29.68224948021748, -23.676965750000022),
              new google.maps.LatLng(29.68224948021748, 44.87772174999998),
              new google.maps.LatLng(71.82725578445813, 44.87772174999998),
              new google.maps.LatLng(71.82725578445813, -23.676965750000022)
    ];


  // Construct the polygon.
  poly = new google.maps.Polygon({
    paths: [worldCoords,EuropeCoords],
    strokeColor: '#000000',
    strokeOpacity: 0.8,
    strokeWeight: 2,
    fillColor: '#000000',
    fillOpacity: 0.35
  });


  poly.setMap(map);
}

You need to make the winding direction of the outer polygon opposite that of the inner polygon and add a point:

var worldCoords = [
  new google.maps.LatLng(-85.1054596961173, -180),
  new google.maps.LatLng(85.1054596961173, -180),
  new google.maps.LatLng(85.1054596961173, 180),
  new google.maps.LatLng(-85.1054596961173, 180),
  new google.maps.LatLng(-85.1054596961173, 0)
];

    poly.setMap(map);
}
initialize();
