[flame_audio] Playback progress can be manually adjusted in iOS browser

### What happened?


As shown in the screenshot, the game's audio can be manually controlled through the Dynamic Island in the iOS browser.

### What do you expect?

I would prefer that the audio controller does not appear, so the audio cannot be arbitrarily controlled, just like in other web-based mobile games.

### How can we reproduce this?

```dart
FlameAudio.play('effect.mp3');
```
- `flutter build web --wasm`
- Used vercel to host game
