WebKit is missing support for Paged Media margin boxes: http://www.w3.org/TR/css3-page/#margin-boxes
This blocks bug 15548
Paged Media features are currently gated on a refactor being completed by Dave Hyatt (http://lists.webkit.org/pipermail/webkit-dev/2012-May/020668.html).
What is the status?
This is blocking wkhtmltopdf to support in-doc headers/footers, and other important standard printing options.
