Ensure that automatic printing still works when the viewer and/or its pages are hidden (bug 1618621, bug 1618955)

Browse source 
Please note that this patch, on its own, won't magically fix all of these printing bugs without [bug 1618553](https://bugzilla.mozilla.org/show_bug.cgi?id=1618553) also being fixed.
(However I don't foresee that being too difficult, famous last words :-), but it will as suggested require a platform API that we can notify when the viewer is ready.)
