Description
Description
I have a form with several fields (TextField) and in the end a button that sends the form data to a server and navigates to another screen if successful.
When I'm clicking the button, I dismiss the keyboard and that is causing the last modified input to be focused (it's scrolled into view). Even if I change the button (a Pressable) to only call Keyboard.dismiss(), this issue still happens.
From what I tested this only happens if I type characters in the input: if I only tap the input so that it has focus, it works fine; if I only delete some characters it also works fine, that is, the input is not focused (and scrolled to) when I call Keyboard.dismiss().
This only happens in iOS (in Android, it works correctly, without scrolling to the input).
It also works if I click in the keyboard "Return" button before clicking the button (it closes the keyboard, but doesn't scroll to the field). If there is a way to trigger it programatically, it could be used as a workaround.

Steps to reproduce
Have a form with several TextField components and a button at the end. Call Keyboard.dismiss() in the button. Make it so that when you go to the end of the screen, the first fields are not visible.
Type anything in one of the first fields (it can be any field, as long as it's not visible in the end of the screen).
Let the keyboard open, then go to the end of the screen and tap the button (you can also tap outside of any field to close the keyboard).
If you are using iOS, the Textfield is focused (the screen will scroll and focus it).

Research direction
Start with the linked Expo Snack and reproduce the behavior on iOS using Keyboard.dismiss() with TextField components and the button or Pressable. Trace the keyboard dismissal and focus behavior from that entry point; done means dismissing the keyboard does not scroll to or refocus the previously edited field.
