They have "(-moz-)box-sizing: border-box" in their UA stylesheet. Relevant  
quote from CSS2.1 17.6.1:

"However, in HTML and XHTML1, the width of the <table> element is the  
distance from the left border edge to the right border edge.

Note: In CSS3 this peculiar requirement will be defined in terms of UA  
style sheet rules and the 'box-sizing' property."
