描述
Description
Render
<Pressable>
<ScrollView>
<Text>Anything tall, worth to scroll through... e.g. 10 paragraphs of Lorem Ipsum</Text>
</ScrollView>
</Pressable>
if you try repeatedly to scroll it on iOS, either on Simulator, or on a real device (tested with iPhone), sometimes it will scroll normally, but half of the time it won't start scrolling on your tap, like if there is an interference between the parent Pressable and the ScrollView. If you turn that Pressable into just a boring View you'll find the scrolling works just fine.
At the same time, on Android it works just fine:
ScrollViewscrolls alrightPressablecaptures (if you add itonPresshandler) on taps outsideScrollView
In other words, on Android it works as if the ScrollView is above the parent Pressable in the view stack when handling touches; and on iOS it works as they are at the same level of the stack, intercepting user touches randomly, one or another.
P.S.: Yeah, I know there is a workaround to render the same like
<>
<Pressable>...</Pressable>
<ScrollView>...</ScrollView>
</>
which works, but I don't see why the problematic variant should not work as well.
Steps to reproduce
Just run the repro app and play with the scrolling.

调研方向
首先在 iOS 上运行 https://github.com/birdofpreyru/rn-scroll-view-bug 中的必需复现程序,并反复滚动 Pressable 内的 ScrollView。跟踪 iOS 对 Pressable 和 ScrollView 的触摸处理,然后验证滚动是否能够可靠地开始,同时 Pressable 仍能处理 ScrollView 外部的点击。
