And more generally, this is yet another example of people thinking of 
"the rendering" as proceeding procedurally when it just doesn't.  You 
can't define that the styles suddenly behave completely differently 
based on what the styles were "in the past".  There is no "past".  You 
have to define the state of things, period, and how states of some 
things depend on states of other things, but with no implied timeflow in 
the process....
