playlists view navigation issue

- open Playlists view
- scroll down to the last playlist entry and click it
- in song list view of the playlist click "back" hardware button
- playlists view is shown again as expected but it is scrolled back to the top

I would expect the playlists view to stay at the last position (bottom in my example). All other views (audiobook, album, artist ...) behave like my expectation.
