Macro prevents correct parsing of class

An imported marco (I simplified the source file), prevented the correct parsing of the following class.

#include <GLFW/glfw3.h>

PXR_NAMESPACE_USING_DIRECTIVE

class Scene
{

};

I know that in the presence of macro a parser almost has no chance to understand C++, but I hope that this failure case may be useful for improving the parser.

translation_unit [3, 0] - [15, 0])
  preproc_include [3, 0] - [6, 0])
    path: system_lib_string [3, 9] - [3, 23])
  declaration [6, 0] - [11, 2])
    type: type_identifier [6, 0] - [6, 29])
    ERROR [8, 0] - [8, 5])
      identifier [8, 0] - [8, 5])
    declarator: init_declarator [8, 6] - [11, 1])
      declarator: identifier [8, 6] - [8, 11])
      value: initializer_list [9, 0] - [11, 1])

Start with the reduced C++ snippet in this issue and inspect how the parser handles PXR_NAMESPACE_USING_DIRECTIVE before the Scene class. Reproduce the shown syntax tree and determine whether the class is parsed correctly after the macro; done means the failure case no longer produces the reported ERROR node.
