PSShouldProcess rule ignores ShouldContinue

Steps to reproduce

# File: c:\temp\Invoke-MVP.ps1
function Invoke-MVP {
    [CmdletBinding(SupportsShouldProcess = $true)] # This line shows an exception
    [OutputType('System.String')]
    Param (
        [Parameter()]
        [switch]$Force # just to hide PSAvoidShouldContinueWithoutForce for this MVP
    )
    {
        if ($PSCmdlet.ShouldContinue('Should I continue','Should I continue')) {
            'I continued'
        }
    }
}

Invoke-ScriptAnalyzer -Path 'C:\temp\Invoke-MVP.ps1'

Expected behavior

No error; using ShouldContinue should be equivalent to using ShouldProcess (for which we don't see this issue).

Actual behavior

PSShouldProcess ルールから始め、Invoke-ScriptAnalyzer を使用して C:\temp\Invoke-MVP.ps1 による警告を再現します。ルールが ShouldProcess と ShouldContinue の呼び出しをどのように検出するかを追跡します。完了の条件は、提供された関数が ShouldContinue を呼び出したときに PSShouldProcess 警告を生成しなくなることです。
