[bug] Tray menu broken on Linux (memory related)

Describe the bug

On linux when using TrayIconBuilder the menu is not shown upon click (left or right), giving this error:

(api:7589): LIBDBUSMENU-GLIB-WARNING **: 19:23:57.784: About to Show called on an item wihtout submenus.  We're ignoring it.

The menu appears if I leak the menu memory with Box::leak(Box::new(..

Reproduction

This is reproducible on Linux using api example.

go into the API example directory: examples/api/src-tauri

comment /removeswitch-menu match, it has nothing to do with menu visibility, but somehow keeps things working by referencing the menus.

  // "switch-menu" => {
  //   let flag = is_menu1.load(Ordering::Relaxed);
  //   let (menu, tooltip) = if flag {
  //     (menu2.clone(), "Menu 2")
  //   } else {
  //     (menu1.clone(), "Tauri")
  //   };
  //   if let Some(tray) = app.tray_by_id("tray-1") {
  //     let _ = tray.set_menu(Some(menu));
  //     let _ = tray.set_tooltip(Some(tooltip));
  //   }
  //   is_menu1.store(!flag, Ordering::Relaxed);
  // }

Run the API app
try to click the tray icon, it won't show up anything

Expected behavior

The menu should show up upon click of the tray icon.

No response

Additional context

When leaking the menu memory it shows up, but it doesn't get refreshed when set again with app_handle.tray().unwrap().set_menu()
