AddDoc error not being caught

Good morning.

In our project, I've been trying to handle the output of an addDoc call using angular/fire. The exception will get caught but not the error thrown by addDoc. When uncommenting the line //throw "patata" the catch block will get executed.

```
async saveProjectTest(projectTracking: ProjectTracking) {
const projectTrackingsRef = collection(this.firestore, 'projecttrackings');
try{
console.log("here1");
//throw "patata";
await addDoc(projectTrackingsRef, projectTracking);
console.log("here2");
}catch(error){
console.log("caught");
};
}
```

I don't know if it is a bug or what it is, but this is specially important since it seems like the appropriate way to handle connection errors and any other kinds of errors in my app. Right now I can only implement the "happy path".

I'm using Chromium v130, angularfire 18.0.1, with Angular 18.1.3, connecting to a docker container running a firebase emulator. When I want to test no connectivity, I take down the firebase container.

Thanks in advance, appreciate your help.

使用所提供的 AngularFire 和 Firestore 模拟器版本，从 saveProjectTest 入口点及其 await addDoc 调用开始。停止 Firebase 容器后重现该情况，将 addDoc 的失败与显式 throw 进行比较，并验证预期错误是否到达 catch 块。
