As I pointed out in
<http://lists.w3.org/Archives/Public/www-style/2011Mar/0059.html>
(just sent to the list a few hours ago), this text does not match any
browser implementation.  In all implementations, if a float would
shrink the available space such that content on the same line that
precedes the float in the source wouldn't fit, the float moves down to
the next line, rather than the preceding content breaking across
lines.
