子应用会在主应用加载的情况下 执行两次app.tsx文件 导致页面加载-销毁-再加载

### Actual behavior

_No response_

### Version of ice.js

### Content of build.json or ice.config.mts

```TypeScript

```

### Additional context

_No response_

Reproduce the issue with ice.js 2.6.10 and React 18.3.1, focusing on the sub-application's app.tsx execution while the main application loads. The issue provides no build.json or ice.config.mts configuration, so first isolate a minimal setup and compare the loading lifecycle. Done means app.tsx runs once and the page is not destroyed and reloaded.
