Keep order of fields when updating a JSON object

[josdejong]

Currently, when you've loaded an object like the following in tree mode:

{
  "one": 1,
  "three": 3
}

and afterwards update this object to the following using editor.update(...):

{
  "one": 1,
  "two": 2,
  "three": 3
}

The new property "two" is added at the end of the rendered fields instead of inserted in the middle: you get the order "one", "three", "two".

It would be neat if the newly added field is inserted in the middle instead, maintaining order of the keys.

This is fixed now in jsoneditor@8.6.2 and web application v5.3.3.
