Testcase

I don't know why show this error. Not every time but appears.

(async function ()
{
    let tabs = {};
    function onTabActivated(activeInfo)
    {
        let id = activeInfo.tabId;
        if (tabs[id] !== undefined && !tabs[id].activated)
        {
            setTimeout(function () {

            console.log(tabs[id]);

            browser.tabs.update(id, {
            loadReplace: true,
            url: "https://google.com"
            });

            }, 100);

            tabs[id].activated = true;
        }
    }
    browser.tabs.onActivated.addListener(onTabActivated);
})();
