xml to js is not converting empty comments

[bobharley]

sample xml:

   <test><!----></test>

output:

{
  "elements": [
    {
      "type": "element",
      "name": "test-child"
    }
  ]
}

expected output:

{
  "elements": [
    {
      "type": "element",
      "name": "test-child",
      "elements": [
        {
          "type": "comment",
          "comment": ""
        }
      ]
    }
  ]
}

Is there an option to do this?
