Steps to reproduce
在父组件中：
let datas1 = {title:"标题1",treeDatas:[
{title:"标题2-1",treeDatas:[]},
{title:"标题2-2",treeDatas:[
{title:"标题2-2-1",treeDatas:[]},
{title:"标题2-2-2",treeDatas:[
{title:"标题2-2-2-1",treeDatas:[
{title:"标题2-2-2-1-1",treeDatas:[
{title:"标题2-2-2-1-1-1",treeDatas:[
{title:"标题2-2-2-1-1-1-1",treeDatas:[
{title:"标题2-2-2-1-1-1-1-1",treeDatas:[]},
]},
]},
]},
]},
]},
]},
{title:"标题2-3",treeDatas:[
{title:"标题2-3-1",treeDatas:[]},
{title:"标题2-3-2",treeDatas:[
{title:"标题2-3-2-1",treeDatas:[]},
{title:"标题2-3-2-2",treeDatas:[
{title:"标题2-3-2-2-1",treeDatas:[]},
{title:"标题2-3-2-2-2",treeDatas:[]},
{title:"标题2-3-2-2-3",treeDatas:[]},
]},
{title:"标题2-3-2-3",treeDatas:[
{title:"标题2-3-2-3-1",treeDatas:[]},
{title:"标题2-3-2-3-2",treeDatas:[]},
]},
{title:"标题2-3-2-4",treeDatas:[]},
]},
]},
{title:"标题2-4",treeDatas:[]},
{title:"标题2-5",treeDatas:[
{title:"标题2-5-1",treeDatas:[]},
{title:"标题2-5-2",treeDatas:[]},
{title:"标题2-5-3",treeDatas:[]},
{title:"标题2-5-4",treeDatas:[]},
]},
{title:"标题2-6",treeDatas:[]},
]};
在子组件中：
props:{
datas:{
type:Object,
default: function () {
return {title:"", treeDatas:[]}
}
}
},
let datas = (props as any).datas;
let rootTree = datas.treeDatas;
subtreeArray = rootTree.treeDatas;
这个版本的vue无法正确在子组件中获得被传入的对象（Object）型数据。
What is expected?
datas.treeDatas应该获取父组件传入的datas对象中的
treeDatas数组
What is actually happening?
这个版本的vue无法正确在子组件中获得被传入的对象（Object）型数据。
