Problem Statement/Rationale

When editing a document in JSON mode or when duplicating a document, any Date type field now shows up as a $numberLong value instead of a UTC date string like before.

Steps to Reproduce

Edit any document in JSON mode with any number of Date type fields

Expected Results

{
  "myDateField": {
    "$date": "2022-04-18T00:00:00Z"
  }
}

Actual Results

{
  "myDateField": {
    "$date": {
      "$numberLong": "1648425600000"
    }
  }
}
