If you navigate back with the Back command (Backspace, mouse button, back toolbar button), all view state should be preserved like scroll position, etc.
If you navigate back by clicking in the tree, it will be a fresh start at the view.
We work like a web browser in this regard.
With that said, I think there may be a bug with the current build that prevents view state preservation when using the Back command. Please try a newer build when it is made available in a week or two.
Thanks.
