Elasticsearch: Bad geopoint field should throw error

If a badly formatted object is passed to a geopoint when indexing a doc, it should throw an error. Instead, any fields after the bad geopoint are just ignored:

PUT /test
{
  "mappings": {
    "foo": {
      "properties": {
        "loc": {
          "type": "geo_point"
        }
      }
    }
  }
}

PUT /test/foo/1
{
  "loc": { "lat": 0, "lon": 0 },
  "tag": "ok"
}

PUT /test/foo/2
{
  "loc": {
    "loc": {
      "lat": 0,
      "lon": 0
    }
  },
  "tag": "not_ok"
}

GET /test/_search?search_type=count
{
  "facets": {
    "tags": {
      "terms": {
        "field": "tag"
      }
    }
  }
}

Result:

{
   "took": 1,
   "timed_out": false,
   "_shards": {
      "total": 5,
      "successful": 5,
      "failed": 0
   },
   "hits": {
      "total": 2,
      "max_score": 0,
      "hits": []
   },
   "facets": {
      "tags": {
         "_type": "terms",
         "missing": 1,
         "total": 1,
         "other": 0,
         "terms": [
            {
               "term": "ok",
               "count": 1
            }
         ]
      }
   }
}
