Add-Type -AssemblyName not taken into account by the completion

I tried to look for the solution in existing tickets, but found no ticket mentioning Add-Type support.

I am using now PSES in Sublime Text with PR and recipe at: https://github.com/PowerShell/PowerShellEditorServices/pull/629#issuecomment-373787797 and I found that it is not completing .NET types loaded by Add-Type e.g.:

Add-Type -AssemblyName System.IO.Compression.FileSystem
[System.IO.Compression.

completes only to types present in System.IO.Compression but not System.IO.Compression.FileSystem, like ZipFile.

Also trying to complete [System.IO.Compression.ZipFile]:: returns nothing. I tried adding explicit path, no effect.

Do I need to explicitly specify additional modules somewhere when starting PSES or it should pick up the Add-Type from my script?

Riproduci il comportamento del completamento in PSES usando Add-Type -AssemblyName System.IO.Compression.FileSystem e gli esempi di System.IO.Compression.ZipFile. Inizia tracciando il percorso del completamento per i tipi .NET caricati. Il lavoro è completato quando il completamento rileva ZipFile e offre i membri dopo il riferimento al tipo, con copertura dei casi segnalati.
