[bug] using http plugin fetch replace window.fetch will cause page freezed

I want to use the fetch provided by @tauri-apps/plugin-http to replace window.fetch to avoid triggering CORS, but if I globally replace it in the following way, it causes the page to freeze.

Additionally, even calling other tauri::commands(such as `invoke('greet', { name: 'tauri' })`) also causes the page to freeze.

```js
import { fetch as tauriFetch } from '@tauri-apps/plugin-http'
window.fetch = tauriFetch
```
