Prerequisites

• I have written a descriptive issue title.

• I have read the troubleshooting guide.

• If this is a security issue, I have read the security issue reporting guidance.

Summary

I am experiencing a problem with Get-Help Get-Help in this extension. I think it should display AllUsersView but It is displaying only partial help.

No source file or test is named. Start with Update-Help, restart Visual Studio Code, and run Get-Help Get-Help in the extension while comparing the standalone PowerShell result; trace the extension's help handling until the installed AllUsersView content is surfaced, then verify the complete help output appears.
