UX recommendation: Navigating up in the browser via shortcut ⌘-↑ (or also button if there would be one (in the future) shall always:

Show the folder you came from in the viewport

Have the folder you came from selected, so that you can instantly move back into it (⌘-↓) or to its siblings (← ↑ → ↓ )
This is currently inconsistent. Please implement the recommendation everywhere.
Reproduction 1
1) Open ~/x/ in a browser window
2) Navigate into folder ~/x/1/ with ⌘-↓
3) Navigate back to parent ~/x/ folder with ⌘-↑
Result:
-

The folder you came from "1" is in viewport and is selected.
-

Instantly move back in or to its siblings.
Reproduction 2
1) Open ~/x/1/ via File > Browse Recent > ~/x/
2) Navigate back to parent ~/x/ folder with ⌘-↑
Result:
-

The folder you came from "1" is NOT in viewport and NOT selected
-

You first have to find it again in order to continue in an oriented manner.
Reproduction 3
1) Open ~/x/1/file.jpg via File > Open… (⌘-O)
2) Navigate back to the parent folder ~/x/
Result:
-

The folder you came from "1" is NOT in viewport and NOT selected.
-

You first have to find it again in order to continue in an oriented manner.
