Cannot document templated using declaration with qdoc

Consider following snippet:

template<typename K, typename T>
struct S {};

template<typename T>
using Specialized = S<int, T>;

Now qdoc does not warn about undocumented typedef and it does not recognize the templated using declaration regardless of syntax. Attempted:

/*!
\class S
\inmodule MyModule
\brief Some struct.
*/

/*!
\typedef template<typename T> Specialized
Desc...
*/

/*!
\typedef Specialized
Desc...
*/

But both syntaxes produce the same error:

(qdoc) warning: Cannot find 'Specialized' specified with '\typedef' in any header file

Placing it inside a class does not help here. Without the template the using declarations are picked up by \typedef command fine.

(it is in the header file with other things that are documented fine)
