A bit weird to have a if for just an ASSERT. I'd better do

ASSERT(!is<CSSPrimitiveValue>(value) || downcast<CSSPrimitiveValue>(value).isValueID());

Seems like you have to indent this return

> Source/WebCore/style/StyleBuilderConverter.h:1175
> +    auto* second = downcast<CSSPrimitiveValue>(is<CSSValueList>(value) && downcast<CSSValueList>(value).length() == 2 ? downcast<CSSValueList>(value).item(1) : nullptr);

Looks like we could store is<CSSValueList>(value) in a boolean since it's also used in the if block above.
