Steps to Reproduce

(Write your steps so that anyone can reproduce the issue in the Snack demo you provided.)

1. write long validation function onScroll for prevent scroll
2. just scroll fast, its scroll the next render item without executing current condition

Start with the linked Expo Snack and reproduce the issue using the onScroll handler, scrollEnabled prop, and a deliberately long validation function. Trace how fast swipes are processed while validation is pending. Done means a fast swipe cannot advance to the next item when validation disables scrolling, while ordinary scrolling still works.
