I don't think it breaks progressive rendering, even on paged media.
On each footnote encountered, browser can check:
if (height_of_static_content + height_of_footnote_area > height_of_page)
I'm thinking that footnotes would be flowed independently of normal
content. Browser would flow normal content from the top of the page, and
flow footnotes from the bottom of the page at the same time. Break when
The only limitation here is that HTML of footnotes section has to be known
in advance to compute styles for footnotes, however
printing-while-downloading seems a bit extreme to me.
