hi, the vega-lite Row & Column Encoding Channels is able to support the nested type field, but the kibana vega does not.

{
  "$schema": "https://vega.github.io/schema/vega-lite/v2.json",
  "data": {
    "name": "temperature",
      "values":[
        
   {
      "Name":"chevrolet chevelle malibu",

      "Cylinders":8,
      "Displacement":307,

   },

   }
       
  ]
  },

and in the kibana vega, it shows error and can not access the field
kibana-vega-lite

after change to flat field, it works fine
kibana-vega-good

BTW, the vega-lite tooltip also doesn't work in kibana-vega!
