Fix minimum height request, handle 0 allocation better
First, fix a problem where though we intended to request a minimum height of 0 for the docs content, we were actually requesting spacing for all items. On low resolution screens, we were still attempting to allocate an item even when we were given 0 height. https://bugzilla.gnome.org/show_bug.cgi?id=596984
