Indentation inconsistent when using more than 1 line continuation

Before submitting a bug report:

• Make sure you are able to repro it on the latest released version
• Perform a quick search for existing issues to check if this bug has already been reported

Steps to reproduce

Execute the following script & compare the formatted output to the input (as defined by the variable $scriptDefinition)

$scriptDefinition = @'
$all_links = `
    [array](Get-ChildItem -Path ([Environment]::GetFolderPath('StartMenu')) -Recurse -Include '*.lnk') + `
    (Get-ChildItem -Path ([Environment]::GetFolderPath('CommonStartMenu')) -Recurse -Include '*.lnk')
'@

Invoke-Formatter -ScriptDefinition $scriptDefinition

Expected behavior

The output of the call to Invoke-Formatter should be the same as the input.

Actual behavior

The third line of the output is not indented to the same level as the second line - the output of Invoke-Formatter is as shown below.

$all_links = `
    [array](Get-ChildItem -Path ([Environment]::GetFolderPath('StartMenu')) -Recurse -Include '*.lnk') + `
(Get-ChildItem -Path ([Environment]::GetFolderPath('CommonStartMenu')) -Recurse -Include '*.lnk')

まず、提供された PowerShell スクリプトを PSScriptAnalyzer 1.18.0 で Invoke-Formatter を通して実行し、複数のバックティックによる継続行がどのようにインデントされるかを確認します。3 行目が 2 行目と同じレベルにインデントされ、フォーマット後の出力が入力と一致すれば完了です。
