Describe the bug

  1. Press and hold the picker.
  2. Scroll Down.
  3. Notice that the picker appears directly below the input.

Expected behavior: The picker should not open when holding and scrolling.

Actual behavior: The picker appears directly below the input when holding and scrolling.

Why is it important? It used to work this way for ages, and we could live with that; but something recently broke, and and now changing the picker in this manner doesn't trigger the onValueChange event. It seems, it was broken in 2.5.0.

I suggest fixing this issue and adding a flag to disable this behavior, as it can lead to unintentional value changes by users during scrolling.
