在Chrome扩展中禁用父上下文菜单

如果我有 Chrome Extension context menu 对于子菜单,我如何禁用父菜单,以便在启用父菜单之前无法访问子菜单项?

chrome.contextMenus.create({
  id: "parentMenu",
  title: "Parent Menu",
  contexts: ["browser_action"],
  enabled: false
});

// Create a submenu with two radio buttons

chrome.contextMenus.create({
  parentId: "parentMenu",
  title: "Submenu1",
  contexts: ["browser_action"],
  type: "radio",
  checked: true,
  onclick: function (evt) {}
});

chrome.contextMenus.create({
  parentId: "parentMenu",
  title: "Submenu2",
  contexts: ["browser_action"],
  type: "radio",
  onclick: function (evt) {}
});

即使parentMenu被标记为disabled(禁用),它也不是disabled(禁用)。当我禁用子菜单时,它们确实会按预期禁用。
