Using static fragments with the CoordinatorLayout of the new design support library

I've been experimenting with the new library suggestions and I just can't wrap my setup around myself the way I want.

I am taking this example code as a reference: https://github.com/chrisbanes/cheesesquare

I was able to add a static slice (contains some FrameLayout with recyclerView and additional empty views) as a child of the CoordinatorLayout, which works as expected when scrolling through the (ugly) recycler view inside it.

Working gist and result:

I am only trying to add one additional CardView above my fragment, which should also have the same effect on the toolbar when dragged upwards. I tried adding them to LinearLayout inside NestedScrollView along with various other combinations, none of which were successful. Whenever I click on a card, they move and never again fall into place. Moreover, dragging the map still disappears from the toolbar, but nothing else happens.

Broken gist and result:
