Description

When I have multiple touch points on Android, events are mistakenly triggered.

In my case, when I place my finger on view A, which is bound to touch events, if I do not release my finger and place another finger on view B, the touch event for view A is triggered again, even though the second finger is on a different view.

I tested the behavior on iOS, and with the same operation, if my other finger is on view B, the touch event for view A is not triggered. Only if the other finger is also placed on view A will the touch event for view A be triggered again.

I also tried using TouchableWithoutFeedback, Pressable, and encountered the same issue on Android.

Steps to reproduce
  1. Install the app
  2. Place one finger on a view that is bound to an event and keep it there, then place another finger on a view that is not bound to any event to reproduce the issue

Comienza con el reproductor obligatorio en yandadaFreedom/reproducer-react-native-0.80.1, instala la aplicación y reproduce la secuencia multitáctil en Android. Rastrea el manejo de los eventos táctiles implicado en TouchableWithoutFeedback y Pressable, y verifica después que un segundo dedo en una vista no relacionada no vuelva a activar la primera vista, mientras que un segundo dedo en la misma vista sí lo haga.
