打开新标签页后，Chrome扩展程序退出运行JavaScript

Question

I am trying to make a chrome extensions, that is started in one tab and continues to run while opening several new tabs. However, it only starts ONE new tab instead of the 5 specified because the script stops running.

The important part:

function launch (url, name, callOnLoad) {
  window.open(url, name)
    .addEventListener(
      "load",
      callOnLoad,
      { once: true, passive: true }
    );
}
async function launchProcess (taburl) {
  const sleep3 = { then(resolve) { setTimeout(resolve, 250); } };
  for (let i = 2; i < 7; ++i) {
    launch(taburl, "tab" + i, proceed);
    await sleep3;
  }
}
launchProcess(taburl) //Taburl is acquired by running a chrome query to find the last active site.

The whole script:

function proceed (evt) {
  console.log("A window has been loaded");
  console.log(evt);
//End of execution
}

async function launchProcess (taburl) {
  const sleep3 = { then(resolve) { setTimeout(resolve, 250); } };
  for (let i = 2; i < 7; ++i) {
    launch(taburl, "tab" + i, proceed);
    await sleep3;
  }
}

async function timer(time) { //timer() is only used if the user activates it, so you can ignore it atm
    const sleep = { then(resolve) { setTimeout(resolve, 15000); } };
    var date = new Date();
    var timestamp = date.getTime();
    timestamp = timestamp + 60000
    while (time > timestamp) {
        date = new Date();
        timestamp = date.getTime();
        timestamp = timestamp + 60000
        await sleep;
    }
    const sleep2 = { then(resolve) { setTimeout(resolve, 250); } };
    var excttimestamp = new Date();
    while (time > excttimestamp) {
        excttimestamp = new Date();
        await sleep2;
    }
    launchProcess().then(console.log, console.error);
}

PS: If someone has some clues on how to make timer() more efficient, help is very welcomed :)

I expect the Function to "launch" multiple tabs and sleep, then opening another tab and running other not mentioned functions. Instead it only opens one and quits.

I found a solution for myself: chrome.tabs.create({url: 'http://www.google.com', active: false}); opens a new tab over chrome but doesn't focus on it, so the popup stays and the code keeps running :)
