There have been many discussions on this subject before. Many flowables have no
natural width so our simple algorithm effectively gives up; I believe it is
slightly cleverer than before and doesn't crash out with tables in tables so often.
Conceivably a Table could pursue a depth first strategy to completion, but if
the lower level flowables contain a paragraph which is naturally unsized then no
benefit will be obtained over the myopic algorithm if the size propagates outwards.
Someone contributed patches to make the distribution of unsizedness more fair,
but without a notion of goodness for the whole (outer) table there's no right
way to do this. I guess that Dinu would prefer the extra space in his example to
be removed in this particular case. That might be possible, but I'm not holding
