C++ Concepts/SFINAE: clang and MSVC/G++ different results for out of line function definition with template and Concept/SFINAE

I am defining a constructors of a class that constrained to check for the type equivalence of the underlying type of passed-in iterator versus the node_type defined in my class, with the help of concepts or SFINAE.

However, no matter how I tried to tweak the code using enable_if and/or concepts, I cannot make all compilers happy with out-of-line definition equal to declaration. Currently below results would yield no errors for MSVC/g++ but clang complains, all using latest version(19.28, 11.1, 12.0 respectively). Can anyone clarify what is wrong here? Code is also available on godbolt with below link. Thanks.

    struct node_type {
        PointND<_Tp, _N> key;
        ElemType value;
    };

    requires std::same_as<typename std::iterator_traits<RAI>::value_type, 
                          typename Tree<_Tp, _N, ElemType>::node_type>
    Tree(RAI, RAI);

Error on this line:
