I think it's pretty clear that we want to avoid hysteresis in our 
rendering (that is, the rendering of a particular DOM with particular 
styles applied must be independent of the path taken to get to that DOM 
and those styles). This may indeed be worth stating as a basic principle 
of CSS, but I thought the formulation of the specification already made 
that clear: when the rules applied to the DOM change or the DOM changes, 
the CSS processing model should be run through again and new results 
computed, since CSS assumes a given set of rules that apply and a given DOM.

Given that, I feel that anything other than just completely rebuilding 
the rendering of the page from scratch is just a UA optimization that 
should have the same effect as said full rebuild would have.
