描述
Description
When having a ScrollView with overflow: 'visible' and some marginTop, this margin is shown on top of the ScrollView content when the end of the ScrollView is reached.
I have been able to reproduce this on a Pixel 6 running Android 13 and Android 14, and on an emulator running Android 12.
It works fine on Android 11.

调研方向
首先在 Android 12–14 上运行链接的 ScrollViewOverflowMargin repository,并使用 overflow: 'visible' 和 marginTop 重现该问题。将滚动结束时的行为与 Android 11 进行比较,然后跟踪 React Native ScrollView 的 Android 实现。当滚动结束时 margin 不再显示在内容上方,同时报告的滚动行为保持不变时,即表示完成。
