Turn off collaboration popup messages asking "do you want to collaborate"

When in a FaceTime call, I will often need to look up some information. As soon as I navigate to Safari, I get a popup asking if I want to collaborate. How can I disable this default annoying popup. If I want to collaborate, then surly it is something that I will select myself. I do not need to be constantly pestered like some child with suggestion about what I may or may not want to do.
