// url.parse `query` field tests — Node legacy url.parse truth:
//   query = search minus the leading '?' (string), null when there is no
//   search; url.parse(url, true) parses it with querystring semantics
//   (decode '+' / %XX, duplicate keys aggregate into arrays).
// Under the old implementation the field was entirely missing (undefined).
