This patch can be tested e.g. with the
sizes.pdf
document in the test-suite.While this patch isn't necessarily the best solution, e.g. it might be possible to solve this with only CSS, it's what I was able to come up with to address an old issue.
The solution here re-uses the
spread
-class in PresentationMode, since that one already takes care of centering pages vertically, together with a dummy-page that takes up the entire height of the window.Finally, some PresentationMode-related CSS-rules are also simplified slightly, since the changes in PR #14112 (using Page-scrolling) allows some clean-up here.
