inconsistent colorization of class and classes in templates

[matter123]

Example code:

template <bool check = !Identity, class = std::enable_if_t<check>>
result_type operator()(argument_type k) {
}
template<class A, class B = C, typename D = E>

class on line 1 has the scope entity.name.type.template.cpp
C and E on line 2 have the scope storage.type.template.argument.C.cpp
