Unwanted Google+ Connection

I started with a fresh installation of the add-on with no dials added yet. I flushed my DNS Resolver Cache so it had no entries. After I added the first dial I went back and checked my DNS Resolver Cache. Along with the expected entries there are also multiple entries to Google+ IP addresses - sometimes as many as 10 different Google+ IP addresses.

I've tried it with many different web sites and have used previews from the dial URL and local image files and always get unwanted connections to Google+. What feature within the Speed Dial add-on is causing the pings to Google and is there a way to disable it in preferences/options?
