【报Bug】UTS中遍历UTSJSONObject iOS和安卓效果不一样

示例代码：

let utsJsonObj = {
name:"zhangsan",
age:"22",
}
utsJsonObj['classInfo'] = "三年二班"
utsJsonObj.forEach(function(perField:any){
console.log(perField)
})

操作步骤：

let utsJsonObj = {
name: "zhangsan",
age: "22",
bb: null
}
utsJsonObj['classInfo'] = "三年二班"
console.log("%%%%%%%%%%%%%%%");
utsJsonObj.forEach(function (perField : any) {
console.log(perField)
})

预期结果：

23:17:04.692 age at pages/UTSDemo/IjkplayerUTS.uvue:85
23:17:04.693 bb at pages/UTSDemo/IjkplayerUTS.uvue:85
23:17:04.693 name at pages/UTSDemo/IjkplayerUTS.uvue:85
23:17:04.693 classInfo at pages/UTSDemo/IjkplayerUTS.uvue:85

实际结果：
