refactor template class is messy

[sd44]

When I use srefactor-refactor-at-point on the class template to generate function impletion,it's always messy.
eg:
testrefactor.h:

template <typename T>
class templateSrefactor {
 public:
  templateSrefactor();
  ~templateSrefactor();
};

the result in testrefactor.cpp is:

templateSrefactor<T>::template <class T> {
  
}
templateSrefactor()
templateSrefactor<T>:: {
  
}
template <class T>
~templateSrefactor()
