Opening GeoJSON file with mixed geometries in QGIS?

If I have a GEOJson file, for example a file named test.js with inside the following:

{ "type": "FeatureCollection",
"features": [
{ "type": "Feature",
  "geometry": {"type": "Point", "coordinates": [102.0, 0.5]},
  "properties": {"prop0": "value0"}
  },
{ "type": "Feature",

  "geometry": {
    "type": "LineString",
    "coordinates": [
      [102.0, 0.0], [103.0, 1.0], [104.0, 0.0], [105.0, 1.0]
      ]
    },
  "properties": {
    "prop0": "value0",
    "prop1": 0.0
    }

  },
{ "type": "Feature",
   "geometry": {
     "type": "Polygon",
     "coordinates": [
       [ [100.0, 0.0], [101.0, 0.0], [101.0, 1.0],
         [100.0, 1.0], [100.0, 0.0] ]
       ]
   },
   "properties": {

     "prop0": "value0",
     "prop1": {"this": "that"}
     }
   }
 ]
}

how to open it with QGIS?

I open QGIS, press "add vector layer", choose "File" but I am not able to open it.

If I choose GEOJson format, my file is not showed in browser window.

If I do not specify input type, I get the error: "your file is not valid or recognized data source".

How have I to format this file?

It seems there is a lack of documentation about this topic.
