Enum wont be selected on load if it not the first element about json-editor

[waltzofpearls]

I encountered the same issue when using enum, enum_titles and choices editor in 2.15.0. The json-editor always has the first item in the list selected. It works fine after I switched back to 2.14.1.

{
  'country': {
    'title': 'Countries',
    'type': 'array',
    'format': 'table',
    'items': {
      'type': 'string',
      'title': 'Country',
      'format': 'choices',
      'enum': Object.keys(countries),
      'options': { enum_titles: Object.values(countries) }
    }
  }
}
