Sure we do.  That's precisely what the "computed value" stage is
*for*.  You can't resolve any property using the "em" unit until
you've computed the font-size property, etc.

Similarly, a property using a variable wouldn't be able to resolve its
computed value until the associated property computes.  (data-*
properties would compute to their specified values, + any variable
calls that they themselves make.)
