Yes, thanks. That is how I understood the bug description. The screenshot I posted is actually using the small paperback format, and demonstrates six footnotes on one page—five of which were printed but the sixth was moved to the following page. That all describes expected behaviour and how things are functioning normally. I could not get a case where footnotes vanished entirely—save for the condition I described here:
@AmberV: I’ve just run a quick test, and if a footnote is actually larger than a page, it does not properly balance it between multiple pages and loses it entirely.
