Make website completely invisible to the user switching to another window or tab. Warning: may break some websites.

Did you know? Website can detect you changing or switching into another tab using many ways of DOM and JavaScript hackery. Some time, using the official Page Visibility API provided by browser, or straight up blatantly using the document's focus/blur event.
This script's aim to prevent that from happening, to prevent the website from knowing when you're switching into another tab or window, while also keeping it minimal and the website mostly functional.
This script could be useful for web anonymity, or... could be used for cheating in an important online test... I don't know.
I would advise you to use this when you really need to, because this script may break some important page function.
Otherwise, Good luck!
