Yes, WeasyPrint is exactly in that spot. (Or was, when I implemented 
block layout and box-sizing.)

If the spec for box-sizing is updated to say that the used values are 
affected, then CSS 2.1 (which refers to the used values) correctly 
defines block layout.

But that may conflict with the desire of "round-tripping" in CSSOM.
