title: Panning google map in CoordinatorLayout causes recyclerview to scroll in android design support library 23.0.1
body: <p>The map is in a collapsingToolbarLayout which is nested in an appBarLayout. 
  In versions 22.2.0 and 22.2.1 of the android design support library, I could pan around the map independently of the coordinatorLayout but in 23.0.1, if i try to pan across the map in the north/south axis, it causes the recyclerview to scroll up/down. Is this a bug or is there a way to pass the touch events from the appBarLayout to the mapFragment?</p>
