[bug] Notifications not working in MacOS

### Describe the bug

I'm using Tauri with Svelte on a MacOS. But I'm having trouble with the `notification` module.

All Tauri APIs are allowlisted in `tauri.conf.json`.

**The code below runs and prints `permissionGranted` as `true` but the `sendNotification`s seem to have no effect.**
```
const notify = async () => {
let permissionGranted = await isPermissionGranted();
if (!permissionGranted) {
const permission = await requestPermission();
permissionGranted = permission === "granted";
}
if (permissionGranted) {
sendNotification("Tauri is awesome!");
sendNotification({ title: "TAURI", body: "Tauri is awesome!" });
console.log(permissionGranted);
}
}

notify();
```
**I also tried using the Notifications API in the Tauri console itself but nothing happens and the created Notification object has no properties.**
```js
Notification.permission; // "granted"
const n = new Notification("New Message", { body: "hello" }); // {} empty object
```

### Reproduction

1. `npm create tauri-app` and initiate with Svelte.
2. `cd` into directory and `npm install`.
3. Add in [notifications logic](https://tauri.app/v1/api/js/modules/notification#sendnotification) to script.
4. `npm run tauri dev`.
5. Notifications are not sent.

### Expected behavior

Notification sent to MacOS.

Reproduce the issue using the notification code, tauri.conf.json, package.json, and the reported macOS environment. Start by tracing the notification API entry point and its macOS path, then compare the native and browser Notification behaviors described. Done means both sendNotification calls produce visible notifications on macOS.
