PowerShell 7.2.6 Move-Item在Windows 10更改文件大小写：Bug还是特性？

在Windows 10系统中使用PowerShell 7.2.6的Move-Item cmdlet时，移动后的文件会采用-Path参数中指定的大小写，而非原文件在磁盘上存储的大小写。Windows文件系统不区分大小写，路径匹配符合预期，但文件大小写被修改的行为未在官方文档中提及。

这种行为在Windows系统中功能上无影响，但PowerShell作为跨平台工具，该行为会对依赖特定大小写的Linux应用造成影响。

示例脚本 #

<# PowerShell Script to demonstrate how Move-Item changes the casing of a file 
   based on the case used in the Path parameter.
#>

$base_dir = '~'
$original_file_name = 'test.txt'
$original_file_path = [System.IO.Path]::Combine($base_dir, $original_file_name)
$search_filename = $original_file_path.ToUpper()        # deliberately change the case of the file
$move_to_path = [System.IO.Path]::Combine($base_dir, 'testsubfolder')   # this folder will be removed so ensure it doesn't match something you already have in your home folder that you want to keep
$cleanup = $true    # set to false to persist files used for testing

# Create a file to test
Set-Content -Path $original_file_path -Value "hello world"

# Setup a subfolder to move the file to
if ((Test-Path -Path $move_to_path)) { Remove-Item -Path $move_to_path }
New-Item $move_to_path -ItemType Directory -Force | Out-Null

# Show the casing of the original file
Get-ChildItem -Path ([System.IO.Path]::Combine($base_dir, '*')) -Filter $original_file_name | Select-Object -Property FullName

# Deliberately case the name of the file differently, starting with a capital 'T'
Move-Item -Path $search_filename -Destination $move_to_path | Out-Null

#Show the casing of the 'moved' file
Get-ChildItem -Path $move_to_path | Select-Object -Property FullName

if ($cleanup)
{
    if (Test-Path -Path $original_file_name -PathType Leaf) { Remove-Item -Path $original_file_name }
    if (Test-Path -Path $move_to_Path -PathType Container) { Remove-Item -Path $move_to_path }
}

执行输出 #

FullName
--------
C:\Users\You\test.txt
C:\Users\You\testsubfolder\TEST.TXT

从输出可见，移动后的文件大小写与-Path参数一致，而非原文件的大小写。特此问询：此行为是Bug还是特性？
