Payload for event has some properties not in an array

[omz13]

Using Quill to create an event, the JSON payload does not appear to be strictly conforming microformats2-json.

{
 "type": [
  "h-event"
 ],
 "properties": {
  "name": [
   "Pancake Night"
  ],
  "start": [
   "2019-12-01T18:00+01:00"
  ],
  "location": "The Kitchen",
  "category": [],
  "end": "2019-12-02T21:00+01:00"
 }
}

The "location" and "end" member values are a string instead of an array of one string.
