Issue Description

$PSScriptRoot is not populated when running a code block (via F8)

I am trying load DLLs that are in the same directory as the PowerShell script and use $PSScriptRoot to get the location for them.

When running the code in PowerShell it's fine, but using VSCode, when running the code snippet via F8, the variable is not populated.

Repro

• Open VSCode and create a PowerShell (.ps1) file
• Add the following command Write-Host "$PSScriptRoot\abc"
• Select the newly created line and Press F8 to execute the PowerShell in the integrated terminal

Expected result:
<full working path>\abc

e.g. If the script I was editing was in C:\Source I would expect the result to be C:\Source\abc

Actual result:
\abc

Reproduce el problema seleccionando la línea de PowerShell y pulsando F8 para ejecutarla en el terminal integrado, utilizando la configuración documentada de Windows y VS Code. Sigue la ruta de ejecución de bloques de código de F8 y verifica que $PSScriptRoot se resuelva en el directorio del script en lugar de producir únicamente \abc.
