Section 17.4 has:

> The computed values of properties 'position', 'float', 'margin-*',
> 'top', 'right', 'bottom', and 'left' on the table element are used on
> the table wrapper box and not the table box; all other values of
> non-inheritable properties are used on the table box and not the
> table wrapper box. (Where the table element's values are not used on
> the table and table wrapper boxes, the initial values are used
> instead.)

Should z-index be added to the list? What about opacity, transform, and 
other properties that can trigger a stacking context? What about CSS3 
properties in general?

The underlying question is: can a table box (not its wrapper) establish 
a new stacking context, or will that always be done by the wrapper?
