It should probably also define what else is hidden.  I wrote a good
bit about "hidden content" in
http://dbaron.org/cdi-req/#restricted-subtrees .  (Maybe that's
defined elsewhere, though.)

For what it's worth, in Quirks mode, Gecko does something quite a
bit more complicated involving a forced line break and indentation,
and makes such dd's display:inline.

It doesn't.  The reality can't be expressed in CSS, although Gecko
attempts to and has some Web-incompatibility as a result.

No, since then any author rules setting background on body would not
get propagatated to the canvas per the rules in
http://www.w3.org/TR/CSS21/colors.html#background .

I think dotted text-decorations (once supported) would be superior
to bottom borders here.
