Skip the first/last visible pages pre-rendering page layouts with "holes" (PR 14131 follow-up)

Browse Source 
This was a stupid oversight on my part, since the first/last visible pages have obviously already been rendered at the point when we're checking for any potential "holes" in the page layout.
While this will obviously not have any measurable effect on performance, we should nonetheless avoid doing completely unnecessary checks here.
