Wrong completion with enum declaration

If we are have:

enum class ParseState { processing,
                        restarting,
                        stop };

and we do the following:

enum class ParseState { <cursor here>[PRESS ENTER]processing,
                            restarting,
                            stop };

that results to:

enum class ParseState {
      processing,
    }
                            restarting,
                            stop };
