Lade zunächst die in den Reproduktionsschritten verlinkte Lösung herunter und führe sie aus. Untersuche anschließend das Elementtemplate von ListView oder GridView sowie die Schaltfläche, die die Sichtbarkeit von TextBlock umschaltet. Reproduziere die fehlende implizite Einblendanimation und bestätige die Korrektur, indem du die Animation innerhalb eines Listenelements beobachtest.
