Mobile browsers already suspended most background stuff, and it occasionally does cause issues like that, but usually it just works.

I learned this out a few years ago when trying to figure out why my metrics sometimes reported mobile visitors with load times of hours or even days... Turns out that they opened the site and then switched tabs/apps before it finished loading. Everything except that metric worked fine. I added a heartbeat just to detect that, and it worked without introducing any extra reloads.

This always drives me mad. It's particularly bad if I'm trying to read content sites on a train or somewhere with patchy reception - open half a dozen tabs to give me something to read while I'm disconnected, and then switch to them only to see the content disappear before my eyes. I'd nominate it as literally the worst thing about mobile browsing
