AndroidTV: wrong order in list when browsing network directory

Description

When browsing some big (30-50 items) directory on a NAS through SMB (can have 1-2 sec delay), sometimes the order of the items in the list or grid is not correct, having some categories (Alphabet selection) multiple times.

This is happening not 100% time but more frequently if the browsing is slow.

Expected behavior

Having a consistent grouping behavior based on first letter

Actual behavior

First-Letter groups can appear at least two times.

Steps to reproduce

Find a slow SMB NAS, add a lot of files and/or directories
Browse

Note: This does not seem to be related to case, or directory/file split.
