Unexpected scroll behaviors when using FlatList

Description

Content teleports to right when over-scrolling, if the content is less.

What I am trying to do? 🤔

Two FlatList components are nested inside a ScrollView for a custom component to emulate a grid like structure.

Example:

_________
         |
         |
[] [] [] | [] []
[] [] [] | [] []
[] [] [] | [] []
[] [] [] | []
         |
         |
▔▔▔▔▔

[] represent grid items and | represents edge of the screen. The items are accessed by scrolling horizontally.

How am I doing this? ❓

export function HorizontalRowList({
    rows, data, renderItem,
    bounces = false,
    itemSeparatorComponent,
    style, columnStyle
}) {
    const columns = divideArrayIntoChunks(rows, data);
    return (
        <ScrollView style={{ ...style, overflow: "hidden" }}
            showsVerticalScrollIndicator={false}
            nestedScrollEnabled={true}
            alwaysBounceHorizontal={bounces}
            bounces={bounces}>
            <FlatList data={columns}
                style={{ borderColor: "blue", borderWidth: 1, overflow: "hidden" }}
                ItemSeparatorComponent={itemSeparatorComponent}
                nestedScrollEnabled={true}
                legacyImplementation={false}
                initialNumToRender={columns.length}
                horizontal={true}
                alwaysBounceHorizontal={bounces}
                bounces={bounces}
                renderItem={(column) => {
                    return <FlatList data={column.item}
                        style={columnStyle}
                        ItemSeparatorComponent={itemSeparatorComponent}
                        legacyImplementation={false}
                        bounces={bounces}
                        renderItem={({ item }) => {
                            return renderItem(item);
                        }} />
                }} />
        </ScrollView >
    )
}

function divideArrayIntoChunks(chunkSize, array) {
    const chuckedArray = []
    for (let i = 0; i < array.length; i += chunkSize) {
        chuckedArray.push(array.slice(i, i + chunkSize))
    }
    return chuckedArray;
}

ScrollView to disable individual vertical scroll bars for the columns when the component has less space.
The first FlatList to enable horizontal behavior of grid
The second FlatList component are columns. The component can be given used to render list of varying sizes.

When the bug occurs? 🪲

The bug happens when data is less and rows to render are more. This causes the array to be chunked in the following way:

[] []     |
[] []     |
[] []     |
[]        |

Steps to reproduce

• Create a new project
• Add the code for HorizontalRowList component given in the description
• Import and add the component in App.js
• Create a random list of strings or any other object
• Pass this list to data attribute of HorizontalRowList
• Set the row attribute in such a way that there is considerable space to the right of the HorizontalRowList
• Try scrolling HorizontalRowList and observe the behavior

Screenshots and Videos

Bắt đầu với ví dụ HorizontalRowList trong App.js và Snack được liên kết, sử dụng React Native 0.73.6 trên Android. Tái hiện trường hợp ScrollView và FlatList lồng nhau, trong đó dữ liệu ít hơn số hàng được yêu cầu, sau đó theo dõi hành vi cuộn. Hoàn tất khi nội dung không còn dịch chuyển tức thời theo chiều ngang trong lúc cuộn quá giới hạn.
