EnterAlwaysCollapsed does not bring back the Toolbar when scrolling down

Question

I'm using layout_scrollFlags="scroll|enterAlwaysCollapsed" with a toolbar minHeight of 0dip, with the intention of only bringing back the Toolbar when my first visible item in the RecyclerView is visible (as opposed to enterAlways, which brings it back immediately whenever the RecyclerView is scrolled up). However, the toolbar is never showing again after I scroll it off the screen. What am I missing?

Please take a look at the design support library sample app: cheesesquare

The proper way to implement your described behavior is to just use the scroll flag by itself:

layout_scrollFlags="scroll"
