The outer border should not be set. The reason is documented in
the HTML 4.01 spec:
   http://www.w3.org/TR/html40/struct/tables.html#h-11.3.1
See also the sample table at the end of the chapter. The 'rules'
attribute is intended to control borders between cells, but not
the outer edge of the table: that is the domain of the 'frame'
attribute, which, since you have set neither 'border' nor 'frame',
defaults to 'none'.

The borders should not go away in Firefox, and I expect the fix
to bug 43178 <https://bugzilla.mozilla.org/show_bug.cgi?id=43178>
will fix this problem.
