Summary

When using #region and #endregion in developing PowerShell code, there is a difference in how code collapse works in ISE vs. VS Code. In ISE, collapsing a region will also hide the endregion line. In VS Code, it will not. This leads to extraneough lines when trying to collapse all regions for easier code viewing.

Steps to Reproduce

Write a region in a PowerShell script within VS Code, example:

#region: Enable archive for each mailbox
if ($mailboxes.count -gt 0) {
    foreach ($mailbox in $mailboxes) {
        try {
            $mailboxOutput = $mailbox | Enable-Mailbox -Archive
            Write-Output "Enabled archive for $($mailbox.DisplayName)"
        }
        catch {
            Write-Output "Failed to enable archive for $($mailbox.DisplayName)"
            Write-Error "Failed to enable archive for $($mailbox.DisplayName)"
            Write-Output $_.Exception
            Write-Output $_.ErrorDetails
        }        
    }    
}
#endregion: Enable archive for each mailbox

When collapsing the region, it will show two lines, not 1

#region: Enable archive for each mailbox
#endregion: Enable archive for each mailbox
