Unregister-EditorCommand doesn't remove command from list

Inizia riproducendo la sequenza «register, list, unregister, list», quindi traccia la gestione dell’elenco dei comandi a partire dal problema in ExtensionService.cs alla riga 146 e in InvokeExtensionCommandHandler.cs alla riga 27. Il lavoro è completato quando un comando non registrato non appare più in Additional Commands e la sua invocazione non produce alcuna eccezione dovuta a una voce obsoleta.

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

When calling Unregister-EditorCommand or $psEditor.UnregisterCommand(), the command remains in the Additional Commands list, leading to duplicate entries when my profile module is re-loaded. When trying to invoke the command afterwards, an exception is thrown, so the command is being unregistered, but it remains on the list.

(note: PowerShell Pro Tools is disabled in my current workspace)

Steps to Reproduce

1. Register any simple command, like `Register-EditorCommand -Name MyCommand -DisplayName "Test Command" -ScriptBlock {$psEditor.Window.ShowInformationMessage("I came from Register-EditorCommand.")}
2. View registered commands with Shift+Alt+S or "PowerShell: Show Additional Commands from PowerShell Modules" to ensure the command is registered
3. Invoke the command to verify it works
4. Unregister the command with Unregister-EditorCommand -Name MyCommand or $psEditor.UnregisterCommand("MyCommand")
5. View registered commands again to find if the command remains

Logs

For whatever reason, even setting "powershell.developer.editorServicesLogLevel": "Trace" and "powershell.trace.server": "verbose", the PowerShell output log looks about the same as when it's set to "Information", despite the Integrated Terminal showing trace information (e.g. "DEBUG: [Trace] Logging started", etc.). Nothing showed up about registering commands or loading modules.

The only thing I could find after unregistering the command and executing it from the list is from the Extension Host log:
