Fix overlapping pages (issue 12551580)

            // In portrait, we want the pages spaced such that there is no

            // overhang of the previous / next page into the current page viewport.

            // We assume symmetrical padding in portrait mode.

            return 2 * getWorkspacePadding().left;

            return Math.max(defaultPageSpacingPx, 2 * getWorkspacePadding().left);

        }
