切换标签时如何防止Chrome扩展程序内容脚本暂停

我开发了chrome扩展程序。像往常一样,我在工具栏中有扩展按钮。在弹出窗口中,我有开始按钮。单击开始时,将发送带有“开始”的消息,并且内容脚本中的某些过程正在启动。问题是当我切换标签页或卷起(隐藏)Chrome时,该过程将暂停。当我切换到扩展名所在的选项卡时-该过程继续执行。为了进行测试,我进行了简单的测试,结果是相同的-脚本已暂停:

var TTT = 0;
function TEST() {
    setTimeout(function () {
        TTT = TTT + 1;
        console.clear();
        console.log(TTT);
        TEST();
    }, 500)
} 

清单:

{
   "background": {
      "scripts": [ "background.js" ]
   },
   "content_scripts": [ {
      "js": [ "libs/jquery.js", "js/js.js" ],
      "matches": [ "\u003Call_urls>" ]
   } ],
   "content_security_policy": "script-src 'self' 'unsafe-eval'; object-src 'self'",
   "description": "DESCR",
   "icons": {
      "128": "images/ic_wmid.png"
   },
   "key": "MIIBIjANBgkqhkiG9w0BAQEFAAOCA98AMIIBC8KCBQEAurLyivtW46v1EZWRUryw0OYepQtEhjOkUixB5tDfXieDCZKQGEzv8ODtaOJKyAe/GEtnYKYJ50RP0FiYUUxk6p7biROiI1yt/YWajE3pVMwe8X2Iwuv2oXaUswSIlydIUkCcyiBVp5XqhCtH4/JA07QlX4g0sy8dyBSz9X0jbGcWMdvmUME52YqbnSCGuzNf/sL0hSv3NJuvG2e/mtnW4Zr9lKUYDfzc0rKOTAvQw7wlrnyFg3oadnuR1KkZM3Zt2vSE2eSlG7HF+8riwzFJZA5SIdN7i7kkXqbuprxs36qv+hJgnl4bIHEiE+MFBjujPRMaO3aFi0wLC3TCaZYIWQIDAHYE",
   "manifest_version": 2,
   "name": "NAME,
   "page_action": {
      "default_icon": {
         "19": "images/icon.png",
         "38": "images/icon.png"
      },
      "default_title": "TITLE"
   },
   "permissions": [ "activeTab", "webRequest", "webRequestBlocking", "tabs", "notifications", "http://*/*", "https://*/*" ],
   "version": "1.2",
   "web_accessible_resources": [ "images/ic_wmid48.png" ]
}

我认为其他任何文件和代码都可能无法触及。
