Description
Currently GA script executes asynchronously while page is loading without a good reason for doing so since there are no custom GA events being tracked when page load is happening or right after it finishes, it's also showing up in Lighthouse score report as a very small main-thread blocker. Performance-wise it would be better to defer the script execution until the page has finished loading
