禁止单击 FinderSync 扩展子菜单

我正在用 Swift 编写一个 FinderSync 扩展，并创建一个像这样的子菜单：

let menu = NSMenu(title: "")
let newsub = NSMenu();
newsub.addItem(withTitle: "Folder", action: #selector(createFolder(_:)), keyEquivalent: "")
newsub.addItem(withTitle: "Empty File", action: #selector(createEmptyFile(_:)), keyEquivalent: "")
let new = menu.addItem(withTitle: "New", action: nil, keyEquivalent: "")
menu.setSubmenu(newsub, for: new)

一切正常，但有一个非常烦人的怪癖。在我在 MacOS 上测试过的任何其他子菜单中，如果单击子菜单行本身（因此不是其条目之一，而是本例中的“新建”），则不会发生任何情况。但不适用于此子菜单。当您单击子菜单而不是像平常一样立即展开子菜单时，上下文菜单会完全消失，并且会发出咔嗒声，表明没有发生任何事情（就像您按下了无效的热键一样）。

如何防止这种情况发生，并使子菜单不可点击？我尝试禁用它，但这会完全禁用子菜单，而不仅仅是使其不可单击。

I am writing a FinderSync extension in Swift, and am creating a submenu like such:

let menu = NSMenu(title: "")
let newsub = NSMenu();
newsub.addItem(withTitle: "Folder", action: #selector(createFolder(_:)), keyEquivalent: "")
newsub.addItem(withTitle: "Empty File", action: #selector(createEmptyFile(_:)), keyEquivalent: "")
let new = menu.addItem(withTitle: "New", action: nil, keyEquivalent: "")
menu.setSubmenu(newsub, for: new)

Everything works fine but there's one very annoying quirk. In any other submenu I've tested on MacOS, if you click on the submenu line itself (so not one of its entries, but "New" in this example), nothing happens. But not for this submenu. When you click on the submenu instead of instantly expanding the submenu as normal, the context menu disappears entirely, and a clicking noise plays indicating nothing happened (as if you press an invalid hotkey).

How do I prevent this, and make the submenu non-clickable? I've tried disabling it, but that disables the submenu entirely instead of just making it non-clickable.
