Answer from a Native speaker

Great question. Yes, "pleasure to" operates like an idiom, although more accurately it is simply a phrase. Saying that it is a "pleasure to" do something is used for emphasizing that you are very happy or proud to do something. In other words it gives you pleasure. "Witness" means to see. So the phrase "pleasure to witness" means it makes you happy to see it. Ex: It is a pleasure to witness your wedding. Ex: It is my pleasure to introduce Mr Jones. Ex: It was a pleasure to help you.
