vtkCommand memory leaks invalid warning
There is a memory leaks from vtkCommand. The caused by the fact that pointer to the "vtkCommand or subclass" array may be different (and it is different). Tested vtk 8.2, Visual Studio 2017 15.9.13
It could be fixed easily by replacing in unordered_map const char* key with std::string_view (for c++17) / std::string key
