Commencez par exécuter le reproducteur Snack obligatoire dans RNTester sur le simulateur iOS et comparez la largeur du Text vide avec Android et le Web. Suivez ensuite le chemin Fabric New Renderer pour la mise en page de Text sur iOS, puis ajoutez ou mettez à jour la couverture de régression afin que le Text central vide ait une largeur nulle, tandis que le texte environnant reste correctement mis en page.
