    good point. I will fix it shortly.

   I will clarify some more in the draft.

   IMHO, the behavior of bfcache (and prerendering) is more similar to
showing/hiding tabs in a user agent, which strictly speaking does not follow
the steps outlined here:
http://www.w3.org/TR/html5/history.html#navigating-across-documents. It just
happens to rely on the forward/backward key. :-) Just my $0.02.
