Which is to say, a T where `is_calculated()` is false. As is becoming a repeating theme with CSS types, we have two states for a FooPercentage that is a `calc()` expression: Either the FooPercentage holds the CalculatedStyleValue directly, or it holds a Foo which itself holds the CalculatedStyleValue. The first case was already handled to return Foo, and with this patch, the second is too. :^)
