I have read the related part of the standard, but it does not define the
correct behavior
in this situation. I also checked three browsers and they handled the issue in
slightly
different ways.
- Firefox and Opera: displays content but no borders
- Chrome: displays content and positive borders

I believe that Firefox and Opera handle the issue properly by consistently not
displaying
borders nor shadows if either the length or the width of the box is negative.
