无法在隐身模式下获得焦点 window

Cannot gain focus on Incognito window

如何将焦点设置为新的隐身模式 window?我无法专注于新的隐身 window。当我设置 'incgonito': false 时我可以获得焦点,但当我将它设置为 true:

时我无法获得焦点
chrome.tabs.query({
                  'active': true,
                  'windowId': chrome.windows.WINDOW_ID_CURRENT
                  },
                  function(tabs) {
                      var url = tabs[0].url;
                      chrome.windows.create({
                                             "url": url,
                                             focused: true,
                                             "incognito": true
                                             },
                                             function(window){
                                                chrome.windows.update(
                                                        window.id, 
                                                        {focused: true})
                                             });
                  }
);

首先我将 window 命名为:

chrome.windows.create(function(window){window.name = "portal";});

然后

window.open("", "portal").focus();
