Section 10.3.5 of CSS2.1 covers this, sort of.  In your testcase the real 
question is what the "preferred width" is.  That's not really defined for a 
block with floating kids, so much.

I seem to recall trying to change things in Gecko so that a block-level child 
after a float child didn't reset the preferred width in Gecko and discovering 
that things got pretty nasty very fast (e.g. depending on what the grandkids 
were), with predictable behavior hard to come by.  So we left it with the simple 
algorithm Firefox 3 uses for now.  I can try to dig up the relevant bug report 
if you think that would be worth it, I guess.
