Custom rule is invoked twice for a single script

I am writing custom rules and I see an error reported twice when there should be just one report.

I invoke script analyzer like this:

#11 PS> Invoke-ScriptAnalyzer -CustomRulePath D:\gh\PesterAnalyzerRules -Path a.ps1

RuleName                            Severity     ScriptName Line  Message
--------                            --------     ---------- ----  -------
PesterAnalyzerRules\Measure-ShouldT Information  a.ps1      3     Pipe a script block to 'Should Throw' or 'Should Not Throw'
hrow
PesterAnalyzerRules\Measure-ShouldT Information  a.ps1      3     Pipe a script block to 'Should Throw' or 'Should Not Throw'
hrow


@ D:\xtmp
#12 PS> cat a.ps1

Describe "a" {
    "b" | Should Throw
}

In a debugger, I noticed my rule is getting called on two different threads.

Comienza reproduciendo el problema con Invoke-ScriptAnalyzer, -CustomRulePath y el ejemplo a.ps1 mostrado en el informe. Sigue la invocación de la regla personalizada a través de los dos hilos observados y verifica que la regla produzca un informe para la única aparición en el script; la salida del comando debería contener un solo diagnóstico.
