Invoke-Formatter loses one level of identation after chain with more than 2 commands and script blocks

Steps to reproduce

Input script, formatted already as expected.

Function a {
    Function b {
        Get-Content blah | ? {
            $_ -match foo    
        } | Set-Content bleh

        $AnotherStatement = 1
    }

    Write-Host "hi"
    b
    exit 1
}

Expected behavior

The example above after formatted looks the same.

Actual behavior

After a chain of more than 2 commands which spans several lines, the formatter loses one level of indentation. Using $(...) triggers the same problem.

Function a {
    Function b {
        Get-Content blah | ? {
            $_ -match foo
        } | Set-Content bleh

    $AnotherStatement = 1
}

Write-Host "hi"
b
exit 1
}

Start by reproducing the reported behavior with Invoke-Formatter and the PowerShell script in the issue, including the multi-command pipeline and the $(...) variant. Trace the formatter entry point and verify that formatting preserves the original indentation of statements following these chains and script blocks.
