No. The 'background' property, when applied to the BODY element (only
when there is no 'background' property applied to the HTML element or it
is, but with a value of 'transparant') is propagated to the *canvas* in
HTML documents.

This is a special behavior for the 'background' property, not for the
BODY element.

Only when that value if not 'transparant' as pointed out above and by
the CSS 2.1 CR specification.

It adds 'padding'. But that is not a very big deal or so.

I can not test with Safari at the moment, but if it does not treat the
BODY element like that, please file a bug. Also file a bug if it does
treat the BODY element like that but propagates the 'background'
property to the canvas in XML context.
