Thanks for the rewrite.  New results look much more promising.

One thing we might want to consider is to merge elements when forcing style
or pushing down style.  For example, if we had "<b>hello </b>world" and
bolded "world", I'd expect to get "<b>hello world</b>" instead of "<b>hello
</b><b>world</b>".  While it's not that much of an improvement in this very
simple case, the effect is obvious when the applied on more complicated

I hope this addresses many of Ryosuke's objections to my previous algorithm.

Yes, it addresses most of my current concerns except StyleWithCSS.  I think
we should just obsolete StyleWithCSS and let it unspecified so that we can
keep it backward compatible.
