Here's some more info:

(emphasis mine)
on the same page, the inital value is defined as 0 for each of the top,
right, bottom, and left. For margin's initial property, it says "see
individual properties".
It is interesting that you can set each of the t,r,b,l and margin will
return undefined. If you ever set margin, margin will return values from
there on. Would it be consistent with jQuery's philosophy to normalize this
and have it work as a getter from the start, or is this 'undefined' behavior
useful/correct?
