Grouping and deriving from a template class leads to "not documented" members.

[michaelcadilhac]

Describe the bug
When using both grouping and templates, Doxygen complains that all but the first element of the group do not have documentation. Documentation is however correctly created (inherited).

To Reproduce

Since it is an extremely short test case, I'll inline it:

/** SA. */
template <typename T>
struct A
{
  public:
    ///@{
    /** Same documentation for all members. Details */
    void f1 ();
    void f2 ();
    void f3 ();
    ///@}
};

/** SB. */
class B : public A<int> {};

Doxyfile:

JAVADOC_AUTOBRIEF  = YES
DISTRIBUTE_GROUP_DOC = YES

Running this, doxygen spits out:

file.cpp:9: warning: Member f2() (function) of class A< int > is not documented.
file.cpp:10: warning: Member f3() (function) of class A< int > is not documented.

Expected behavior
f2 and f3 are documented, this warning should not appear.

Version
1.12.0 on Arch Linux latest from official sources.

[albert-github]

It looks like that for templated classes the function hasUserDocumentation() as used in void MemberDefImpl::warnIfUndocumented() const does not know that there is brief and detailed documentation available, better said there is no DeepCopyUniquePtr<DocInfo> available for f2 and f3 in case of a templated class.
In case of a "normal" class all looks like to be OK.
