[alibaba/fastjson]2.0.5 版本，json 转换字段排序 Feature.OrderedField 失效

        String json = """
                {
                    "head": {
                        "requestTime": "1654070371884",
                        "merchantcode": "111",
                        "ticket": "111",
                        "version": "1.0.0"
                    },
                    "body": {
                        "phone": "111",
                        "type": "1",
                        "ticket": ""
                    },
                    "sign": "111"
                }
                """;

        System.out.println(JSON.parseObject(json, Feature.OrderedField));

输出为

{
    "head": {
        "requestTime": "1654070371884",
        "merchantcode": "111",
        "ticket": "111",
        "version": "1.0.0"
    },
    "sign": "111",
    "body": {
        "phone": "111",
        "type": "1",
        "ticket": ""
    }
}

期望顺序不改变，但实际结果是顺序发生了改变。1.2.60 版本不存在此问题
