Description
### 问题描述
*在使用JSONObject.parseObject()反序列化时,会丢失部分字段*
### 环境信息
*请填写以下信息:*
- OS信息: [Windows 11 13th Gen Intel(R) Core(TM) i5-13500H 2.60 GHz 32 GB]
- JDK信息: [JDK 17.0.6]
- 版本信息:[Fastjson2 2.0.56]
### 重现步骤
*如何操作可以重现该问题:*
```java
public static void main(String[] args) {
String json = "{\"algorithmConfig\":[{\"name\":\"你好\"}],\"algorithmSetting\":[{\"kpDeltaTemp\":2,\"kiDeltaTemp\":0.2,\"kdDeltaTemp\":3}]}";
JSONObject parsedObject = JSONObject.parseObject(json);
System.err.println(parsedObject.toJSONString());
}
```
### 期待的正确结果
对以上json进行反序列化后,不会丢失 kiDeltaTemp 、kdDeltaTemp 字段
### 相关日志输出

#### 附加信息
*如果你还有其他需要提供的信息,可以在这里填写(可以提供截图、视频等)。*

Research direction
Start by running the issue's Java example with Fastjson2 2.0.56 and compare the printed JSON with the expected fields. Then trace the behavior from the mentioned JSONObject.parseObject() entry point; done means the output retains kiDeltaTemp and kdDeltaTemp.
