Because we store calculations as a tree of CalculationNodes inside a CalculatedStyleValue, instead of a tree of StyleValues directly, this implements a create_calculation_node() method on CSSNumericValue. CSSMathValue::create_an_internal_representation() then calls create_calculation_node() on itself, and wraps it in a CalculatedStyleValue. Lots of WPT passes again! Some regressions, which are expected: `cursor` fails a test for the same reason it fails other that set it to some kind of numeric value: We don't distinguish between "can contain a number" and "can accept a number by itself". This will affect any similar properties, but overall this is a big improvement.
