Summary

If you are joing a Visual Studio LiveShare Session and use a shared terminal / PowerShell Extention, the terminal does not display the typed text and return values correctly until you resize the terminal (either on host (resize the terminal width) or joiner side (by using toggle content with).

Moreover, the parameter help generation generates the documentation block of the function on the cursor position of the host, if he is in a different file. However, if he is in the same file he is auto focused on the position of the joining person and it gets generated correctly.

I am aware that the issue is related to both PowerShell Extension and VSCode Liveshare, but @SydneyhSmith told me to just raise an issue here.

The issue exists both with the current version of VSCode (1.79.2) and VSCode Preview (1.80.0-insider).

Steps to Reproduce

Terminal pyramid

do not resize the terminal, otherwise the error does not occur

• connect to liveshare
• make the terminal read write
• the joining person types something in the terminal

Parameter help

• Connect to a live share session
• create two different file
• the sharing person goes to the other file and places their cursor in a random position
• the joining person types "##" in a function above the parameter block to autogenerate the parameter help
• The parameter help is generated at the cursor of the generating person

Visuals

If you are using a shared terminal in VSCode Live Share sessions, the PowerShell extension behaves quite weirdly on the joiners side:

on the side of the sharing person it looks ok though:

After you click:

it works just fine:

Additionally, if you whish to have your parameter help auto-generated (using "##"), then it generates the content in the wrong place (where the cursor of the sharing person is):
