Linking header position to an empty entry in the recyclerView, instead of calculating the vertical scroll position. This allows the header to be in sync with the recyclerView scroll and item animations Other simplifications: > Moving top collapse handle out of header view (it doesn't scroll) > Removing background clipping logic from full-sheet > Moving tab bar inside the header view Bug: 196464142 Test: Verified on device Change-Id: Iae5a0ae9af7ce258e1b391b8e85c5c270fe56197
