How to prevent chrome extension content script pausing when switching tab

问题

I develop chrome extension. As usual I have extension button in the tool bar. On the popup I have start button. When click start then message with 'start' is sending and some process in the content script is starting. The problem is that when I switch tab or roll up (hide) the chrome - the process is paused. When I switch to tab where extension is - the process continue executing. For testing I have made simple test, the result is the same - script is paused:

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

manifest:

{
   "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'",

   "icons": {
      "128": "images/ic_wmid.png"
   },

Any other files and codes I think may not touch this.
