Chrome套接字API现在对我不起作用。
我有以下清单：

{
 "name": "My name",
 "version": "0.1",
 "manifest_version": 2,
 "background": {
  "page": "background.html"
  },
 "browser_action": {
  "default_icon": "ico16.png",
  "default_title": "My extension",
  "default_popup": "popup.html"
  },
  "description": "bla bla bla",
  "minimum_chrome_version": "23",
 "icons": {
    "ico128": "ico128.png",
    "ico16": "ico16.png",
    "icon_logo": "icon_logo.png"
  },
 "options_page": "options.html",
 "permissions": ["experimental",
                 {"socket": [
                     "udp-send-to"
                   ]},
                  "notifications",
                  "background"]

}

但在加载扩展时会显示以下警告：

指定的套件类型（布景主题、应用程序等）不允许使用'socket'。

我已经使用版本23.0.1246.0 canary和23.0.1246.0 dev-m进行了测试
