[FEATURE REQUEST] Maintain scroll position in file list

Is your feature request related to a problem? Please describe.
When drilling down larger file hierarchies, e.g. in my large music library, and then backing up a level, the scroll position is lost.
E.g. I would go to Zap Mama/Seven/mp3/01-Jogging in Tombouctu.mp3, then back up (using the android back button or the app's own back button) to the Artist level (Zap Mama), the view starts with the first entry on top again, e.g. Aaron Nevile. It would take quite some time to scroll back down to a later artist, e.g. Züri West.

Describe the solution you'd like
The scroll position should be kept for each folder/directory level separately.

Describe alternatives you've considered
I always need to scroll, or I would make a deliberately steeper hierarchy, which is really just a workaround.

Additional context
Try for yourself with a large, flat hierarchy, the problem is obvious. This has never altered for years, so it's not really a (regressing) bug, but it heavily hampers the user experience for power users.
