[issue37838] typing.get_type_hints not working with forward-declaration and decorated functions

New submission from Netzeband : When decorating a function and using a forward declaration as type hint, the typing.get_type_hints function does not work anymore, since it cannot find the forward declared name in the namespace. After debugging I think, the typing.get_type_hints function is
