Description
Programmatically controlled ScrollView reacts with some shift when user remove finger from the main ScrollView. Same behavior with FlatList. In the video, you can see bouncing when dragging is over, and its absence if you do not take your finger off the screen. This behavior is observed on Android, it works fine on iOS.

Expected behavior
Synchronized movement of ScrollViews during all scroll events
Actual behavior & steps to reproduce
Synchronized movement of elements work fine only on drag, and buggy from drag end till scroll end. You can get rid of this if you set
"decelerationRate={1}"
, but this is not the behavior that is expected.Snack or minimal code example
It's not obvious to look at the ScrollView, and so I add elements that should stay on the left side of the screen when scrolling.
