eruda 插件中使用 chobitsu 无法监听 XhrRequest

```js
    const req = ((xhr as any).chobitsuRequest = new XhrRequest(
      xhr,
      method,
      url
    ))
```

```js
    const req = new XhrRequest(
      xhr,
      method,
      url
    ))
((xhr as any).chobitsuRequests ? ((xhr as any).chobitsuRequests.push(req) :  ((xhr as any).chobitsuRequests = req
```
