Integrated Console - Write-Progress messes things up

[Tiberriver256]

Issue Description

Running a script with Write-Progress screws up the console.

Example Script

function MyAwesomeScript {

	[CmdletBinding()]
	param (
		[Parameter()]
		[string]
		$Name
	)

	$WelcomeMessage = @();

	for ($i = 0; $i -lt 50; $i++) {
		Write-Progress -Activity "Getting ready to greet you!" -PercentComplete ($i/50*100)
		$WelcomeMessage += "Hello $Name"
	}

	$WelcomeMessage
}

MyAwesomeScript -Name Micah

Expected Behaviour

Should look like this (example taken from pwsh running in VSCode):

Actual Behaviour

Looks like this:

The prompt is getting rendered towards the top instead of at the end of the content

That is indeed a bug, thanks for reporting it. It's unfortunately a bit difficult to fix as its a custom PowerShell host. We will look into this.

@rjmholt thinks this a race condition between Write-Progress and the printing of the prompt. This may be fixed by PowerShell/PowerShellEditorServices#1295

Hello, and thank you for your patience! The latest PowerShell Preview for VS Code is now out, and includes the reworking of our pipeline and threading architecture in PowerShell/PowerShellEditorServices#1295. Could you verify if this issue still reproduces using v2021.10.3-preview? Please note that this preview is likely to include other bugs, and you should feel free to file new issues for those so we can work through them. Thanks again!

Thanks for reaching out. Looks like it's still an issue in the preview version.
