Issue Description

Create a PowerShell file, input following script, and hit Alt+Shift+F. The pipe operator in $a | ForEach-Object { $_ } is removed.

$a=@('a','b','c')
$b=@{
    a=1
    b=2
    c=3
}
$b | Select-Object -Property ($a | ForEach-Object { $_ })

Related settings in settings.json:

    "powershell.codeFormatting.trimWhitespaceAroundPipe": true,
    "powershell.codeFormatting.useCorrectCasing": true,
    "powershell.codeFormatting.whitespaceBetweenParameters": true,

Expected Behaviour

The format result should look like:

$a = @('a', 'b', 'c')
$b = @{
    a = 1
    b = 2
    c = 3
}
$b | Select-Object -Property ($a | ForEach-Object { $_ })

Actual Behaviour

The format result is (note that the | is missing):

$a = @('a', 'b', 'c')
$b = @{
    a = 1
    b = 2
    c = 3
}
$b | Select-Object -Property ($a ForEach-Object { $_ })

Riproduci il problema del formatter usando lo script PowerShell e le impostazioni di formattazione mostrati nell’issue, quindi traccia il punto di ingresso della formattazione PowerShell che gestisce le espressioni pipe annidate. Il lavoro è completato quando il | interno viene preservato nell’output formattato e un test di regressione copre questo esempio; l’issue non indica alcun file sorgente né alcun test esistente.
