Summary

My vscode-powershell extension updated this morning to ms-vscode.powershell@2022.6.1 and I'm having an issue where the selection of code I'm running with F8 is executed but then is recalled immediately into the integrated console prompt.

Example:

=====> PowerShell Integrated Console v2022.6.1 <=====

PS> $PSVersionTable

Name                           Value
----                           -----
PSVersion                      7.2.2
PSEdition                      Core
GitCommitId                    7.2.2
OS                             Microsoft Windows 10.0.19042
Platform                       Win32NT
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0…}
PSRemotingProtocolVersion      2.3
SerializationVersion           1.1.0.1
WSManStackVersion              3.0

PS> Write-Output -InputObject "Hi!"
Hi!
PS> Write-Output -InputObject "Hi!"

It's as if the console history is being immediately recalled into the console prompt without additional input.

Rolling back to ms-vscode.powershell@2022.5.1 fixes the issue:

=====> PowerShell Integrated Console v2022.5.1 <=====

Hi!

The latest preview extension ms-vscode.powershell-preview@2022.6.2 exhibits the same behaviour as v2022.6.1.

Could this be caused by PowerShell/PowerShellEditorServices#1823?

Thanks @dbrennand - I am having the same issue on multiple systems.

[andyleejordan]

I think you're probably right about it being PowerShell/PowerShellEditorServices#1823. /cc @SeeminglyScience

[andyleejordan]

I'm having trouble reproducing this. Can you share more environment info? @SeeminglyScience sees it only after first causing an error in the PSIC, but neither of you mentioned this. I'm using PS 7.2.4 on macOS.

[andyleejordan]

Ok seems to be Windows-only? Repro'd (without throwing an error first) on PS 7.2.4 on Windows.

To me it was on a Windows Sever 2019 and WS2022 - brand new session, just after upgrading - the F8 button started pasting the code "twice" as @dbrennand explained.

And

It is also worth mentioning that I can repro it on Windows PowerShell 5.1 on the same boxes :-)

Reproduced on a different Windows system than I initially submitted the issue on:

Windows 10 21H1 (OS Build: 19043.1766)
