[bug] Panic while firing menu event when window is minimized on macOS.

[sprout2000]

Describe the bug

Selecting a menu (e.g. Open...) when a window is minimized in macOS causes the application to panic.

Reproduction

1. Use the template with the default selected.

npx create-tauri-app

2. src-tauri/src/main.rs:

use tauri::api::dialog;
use tauri::{CustomMenuItem, Menu, Submenu};

fn main() {
    let menu = Menu::new().add_submenu(Submenu::new(
        "File",
        Menu::new().add_item(CustomMenuItem::new("open", "Open...")),
    ));
    tauri::Builder::default()
        .menu(menu)
        .on_menu_event(|event| {
            if event.menu_item_id() == "open" {
                dialog::FileDialogBuilder::new().pick_file(|f| {
                    if let Some(fpath) = f {
                        println!("{:?}", fpath);
                    }
                })
            }
        })
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

3. Launch that app and minimize its window.

4. Select Open... from the Window menu.

Expected behavior

Do not fire CustomMenuItem events when the window is minimized.
Or implement window.isMinimized() so that the developer can detect the state of window minimization.
