Steps to reproduce

你们不充许放截图，截图就一目了然了。

var data = {
    "name": "flare",
    "children": [
        {
            "name": "data",
           /* "children": [先保留这段代码，然再注释这段代码（其他的化data多余的代码都去除，再注释这段才会看到效果），这里显示图就不正确了，有一些多余的线段
                {
                    "name": "converters",
                    "children": [
                        {"name": "Converters", "value": 721},
                        {"name": "DelimitedTextConverter", "value": 4294}
                    ]
                },
                {
                    "name": "DataUtil",
                    "value": 3322
                }
            ]*/
        }
    ]
};

What is expected?

正确显示（没有多余的线段）

What is actually happening?

有多余的线段

---

当children有多个节点时，突然把这个children清空了，就会出现这种情况
