Steps to reproduce

I have many PSDrives created that are just aliases to various folders on my c: drive. I'm finding now that when i type a ps drive path and use tab completion, the path changes to the fully converted path - which really hinders the experience of using aliased drives.

I'm pretty sure that this just materialized in the latest preview release - maybe related to #19489?

Expected behavior

New-PSDrive -name asdf -psprovider FileSystem -root C:\Windows
cd asdf:\<tab>  #change to asdf:\<foldername>\

Actual behavior

New-PSDrive -name asdf -psprovider FileSystem -root C:\Windows
cd asdf:\<tab>  #changes to c:\Windows\<foldername>\
