Reproduziere das Problem, indem du die App startest und auf die Home-Schaltfläche klickst, während du dich bereits auf der Home-Seite befindest. Verfolge den Einstiegspunkt der Home-Navigation und überprüfe, dass der Fix verhindert, dass eine doppelte Navigation und ein Back-Stack-Pfeil angezeigt werden.
