The point here you can't even do a reliable timer with userland + `backgroundTimeout`. With userland-only it's even worse.

So the argument is to make this `timeout`, not `backgroundTimeout`. An uncacenlled fetch will activate on this timer whether the page is visible, invisible, frozen or in BFCache.
