Commencez par la reproduction minimale liée et reproduisez la boîte de dialogue sur un iPhone 7 ou un iPhone 8 exécutant iOS 15, en passant du mode portrait au mode paysage. Suivez le comportement de platform-browser et de la boîte de dialogue Material autour des boutons d’action ; le travail est terminé lorsque les boutons restent visibles et que l’espace vide en bas a disparu en mode paysage.
