> Chrome, the various Chromium variants, and Safari will heavily throttle
> JavaScript timers within background tabs and windows. This prevents the
> tunnel from issuing its keep-alive ping and may result in a disconnect. See:
> * https://developer.chrome.com/blog/timer-throttling-in-chrome-88/
> * https://github.com/SignalR/SignalR/issues/4536
> It's possible that there is a way to work around this and continue sending
> keep-alives in the background, such as by simply changing the originating
> event of those timers:
