[Feature] changing visibilityState

See original GitHub issue

Being able to change document.visibilityState (and consequently document.hidden) would be nice:

to test what some code does when hidden, prerender or visible
to test visibilitychange events and how code behave w.r.t. those properties

It should work with Object.defineProperty(document, 'visibilityState', {get() { return "prerender";}}) i don’t know why i opened that issue. Closing.
