[bug] tray disappears in macOS

[codelover2k]

Describe the bug

The tray in macOS behaves inconsistently. It appears and disappears unpredictably under these circumstances:

• When I run or build the app, the tray sometimes disappears.
• Changing the title in the setup causes the tray to vanish, but also not always.
• Restarting macOS temporarily resolves the issue, but after a few app restarts or recompiles, the tray disappears again.

Additional observations:

• Occasionally, the tray reappears if I wait while the app is still running.
• No errors or panics are logged during these events.

Reproduction

#[tauri::command]
fn change_tray_title(app_handle: AppHandle, title: String) {
    println!("title from frontend: {}", title);

    let tray_handle = app_handle.tray_by_id("tray").unwrap();

    if let Err(e) = tray_handle.set_title(Some(&title)) {
        eprintln!("failed to set title: {}", e);
    } else {
        println!("title set successfully to '{}'", title);
    }
}

Expected behavior

tray should not vanish on title or icon changes
