Bug: Entering a directory with keyboard Enter causes focus loss of the directory pane.

[cos1110]

Description

When you enter a directory using the Keyboard 'Enter' key, causes loss of focus of the directory pane, as well as deselection of the first directory item.

Steps To Reproduce

Example of directory structure:

A
  A1
     Target
  A2

1. You see directory A and have it selected, you press 'Enter'.
2. Now you are inside A and you see directories A1 and A2.
3. Chances are that you have lost the focus from the directory pane.
4. See the workaround bellow to navigate to the Target directory.

WORKAROUND

1. Press Tab once to restore focus to the pane.
2. Press Down (you are on A2) to invoke a keyboard update event.
3. Press Up (you are on A1) to update.
4. Now you have both the pane active and the item A1 selected.

Requirements

When you press Keyboard Enter in order to enter a directory, the directory pane should remain focused. This would allow fast keyboard-based navigation with keys Enter | Up-Down | Alt-Up.

Interestingly, this seems to depend on the directory. It's working fine if I use the enter key to open C:\Windows, but I can reproduce the issue in C:\Users.

If I open a directory from the left-hand sidebar, the focus is correctly moved to the file area.

This is a regression from earlier versions of Files where this worked as expected.

It seems to work fine if the folder has 32 items or more. And this number seems to depend on this code.

Files/src/Files.App/Utils/Storage/Enumerators/Win32StorageEnumerator.cs

Line 114 in f5d3d0f

if (intermediateAction is not null && (count == 32 || sampler.CheckNow()))

But I have no idea why this happens.

@cos1110 this issue is fixed in the dev branch and will be included in the next release.
