Found a Datasette 1.0 bug: the ?_extra=columns parameter causes all rows to return `"column-name": "column-name": https://latest.datasette.io/fixtures/attraction_characteristic.json?_extra=columns&_size=1

{
  "ok": true,
  "next": "2,2",
  "columns": [
    "pk",
    "name"
  ],
  "rows": [
    {
      "pk": "pk",
      "name": "name"
    }
  ],
  "truncated": false
}

Should return this:

{
  "ok": true,
  "next": "2,2",
  "columns": [
    "pk",
    "name"
  ],
  "rows": [
    {
      "pk": 2,
      "name": "Paranormal"
    }
  ],
  "truncated": false
}
