### Reproduction Example/SDK Setup

https://github.com/cobyeastwood183/angular

[error.json](https://github.com/user-attachments/files/18612067/error.json)
```json
{
"headers": {
"headers": {},
"normalizedNames": {},
"lazyUpdate": null
},
"status": 0,
"statusText": "Unknown Error",
"url": "http://some.example.com/test",
"ok": false,
"name": "HttpErrorResponse",
"message": "Http failure response for http://some.example.com/test: 0 Unknown Error",
"error": {
"isTrusted": true
}
}
```

### Steps to Reproduce

1. npm install
2. add DSN
3. npm start
4. visit http://localhost:4200/test
5. click button "Test API 2(Localhost)"

### Expected Result

Expect a HttpException to be captured for [HttpErrorResponse](https://angular.dev/api/common/http/HttpErrorResponse).

### Actual Result

Instead 'unknown' is captured when caught by the ErrorHandler or 'Object.error' when caught by calling captureException.
