[CSS21] Height of table wrapper box is not defined by 10.6

The height of a table wrapper box is not defined by 10.6.  I believe it 
should fall into 10.6.6 (both for inline-table and table), so that 
section needs expanding.


Note also that 10.6.3 concerns block-level non-replaced elements in 
normal flow when 'overflow' computes to 'visible', but it fails to 
exclude table boxes.  I suggest adding a statement to the effect that 
the height of table boxes is defined in Ch.17.  Proposal:

In the second paragraph of 10.6.3, replace

   # If 'height' is 'auto', the height depends on whether the element
   # has any block-level children and whether it has padding or borders:

with

   | If 'height' is 'auto', the height is calculated per 17.6.3 in the
   | case of table boxes, and otherwise as follows:


Finally, 10.6.6 is entitled "Complicated cases" which is both vague and 
misrepresentative; non-replaced BFCs are amongst the _simplest_ elements 
to deal with!  I suggest calling it "Remaining cases involving block 
formatting roots".
