<input foo="" />

{
  "start": 7,
  "end": 13,
  "type": "Attribute",
  "name": "foo",
  "value": []
}

Unexpected : value is undefined

Expected

"value": [
  {
    "start": 12,
    "end": 12,
    "type": "Text",
    "raw": "",
    "data": ""
  }
]

This now parses as (an array containing) an empty string in 3.40.2.
