Comment 30 for bug 747197

Andrew, the <td background="foo"> thing should be a separate bug. See
http://lxr.mozilla.org/seamonkey/source/embedding/components/webbrowserpersist/src/nsWebBrowserPersist.cpp#1807
-- we basically never check for background attrs on <td> nodes. That should be
simple to fix. If we don't have a bug on that already, file one on me.
