The fact that the organisation not only has people who are like this in a professional setting working there but also tolerates it doesn't reflect very well on the organisation. I understand it's difficult to control for the variation in personalities working at a large company but it's not too difficult to set a culture where a base level of professionalism is expected and is the norm. I'm not sure of how reviews work at your company but I sincerely hope comments like this officially flag the person as not suitable for management and possibly not suitable to continue in long term service at the company.
