Description

React Native pressables don't seem to prevent the touches from being forwarded to the OS. This results in unexpected behavior in some situations.

e.g. on iPadOS, there is a large area at the top of the screen that can be tapped to scroll to the top. This area usually covers a similar height to the header bar. If headers have buttons that use pressables, the pressable handles the action, but iPadOS also handles the touch and scrolls any scrollview in the screen to the top.

This does not happen when using a native control (e.g., with UIControl), and only happens with React Native's Pressable. It is very common to add custom buttons to the header (even when using native stack and native header), many people also use custom headers. So the unexpected scroll to top results in a bad UX.

I'm not aware of a way to prevent this behavior right now.

Steps to reproduce
  1. Install the app on iPad simulator with yarn ios
  2. Scroll the scrollview so it's not at the top
  3. Click on the button in the header
  4. Observe that the button also scrolls the scrollview to the top
React Native Version

  4. Abre un pull request que haga referencia al número del issue.

Línea de trabajo

Comienza con el reproductor obligatorio en https://github.com/satya164/iPadTouchableRepro y reproduce el comportamiento de iPadOS descrito en el issue; después, sigue el manejo de toques de iOS de Pressable. No se indica ningún archivo de origen ni ninguna prueba; se considera terminado cuando activar un Pressable ya no desencadena también el comportamiento de desplazamiento al inicio de iPadOS, mientras los controles nativos no se ven afectados.
