When trying to tab through the parameters of Get-ChildItem it does not suggest most of the switches and also skips the Attributes parameter if the Path parameter contains the character : which it pretty common for paths.

It only occurs when the : is written as a string in the command line, so using a variable that has the path with the : in it works fine, also any path written without : like \.

If you type the fist letter of the parameter then is suggests it correctly, like -D[tab] will complete to -Directory as expected, but it should still suggest them when tabbing through the parameters.

This has negative effects in editors like VSCode also since it is PowerShell that is reporting the completion data to the editor i believe.

I see this error on all version of PowerShell I have available, 5.1, 6.21 and 7.0.0 Preview 1

• When Path contains ":"
  
• When Path does not contain ":"
  

Parameters that it fails to suggest:

• Attributes
• FollowSymlink
• Directory
• File
• Hidden
• ReadOnly
• System

Steps to reproduce

Get-ChildItem -Path "c:\" -[tab][tab][tab][tab]...

Expected behavior

Get-ChildItem -Path "c:\" -Directory

Actual behavior

Get-ChildItem -Path "c:\" -Depth
