Expected behavior:

• The user opens the Favorites tab and sees the root favorite folder.
• The user navigates into a favorite folder and sees the files and subfolders that belong to that favorite folder.
• When the user goes back, they must return to the root favorite view and see the root favorite folder again.
• This is the same for the Shared tab and the All Files tab.

blue-Light-Screenshot test failed, but no output was generated. Maybe a preliminary stage failed.

When the user goes back, they must return to the root favorite view and see the root favorite folder again.

@alperozturk96 When navigating via favorite into a subfolder navigating back up navigates you through the folder's hiearchy

Isn't it expected behavior? Since favorites, shared are shortcuts and go up means navigate one folder level up. Because user choose to go to subdirectory of some favorite folder from favorite root.

Favorite root:

A
B (A/B)

If user chooses B directly from Favorite root, one level up is A not root favorite again?
