Parser: Strange behavior with enums

#define NOTHING(ARG)

enum Foonum
{
  A = 0,
  B = 1
  NOTHING(Foonum)
};

struct foo
{
  int bar;
};

struct baz
{
  foo Foo;
};

int main()
{
  foo Foo;
  return Foo.bar;
}

All symbols are colored in purple, including Foo and bar. In my project (couldn't reproduce with a MWE), Follow Symbol on foo jumps to its appearance on another struct (like baz.Foo in the example).
