Comment 4 for bug 1856472

Thank you, I would be delighted if you would make my requested change at least optional.

Perhaps a simpler, more general description of this change: when in paged mode, and when navigating backward through the book (regardless of whether one has previously navigated forward or how recently they did), and crossing a boundary into the previous chapter, calculate the number of pages in the previous chapter, and fill the screen with pages from the end of the previous chapter and with blank pages as appropriate for the user's pages-per-screen setting, to make it the same as what the user would see if they had navigated forward through the previous chapter to its end.

My goal is consistency of view no matter in which direction one navigates, or when they navigate.

Thank you.
