[iOS] `<ScrollView>` struggles inside a `<Pressable>` (while it works just fine on Android)

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:

• ScrollView scrolls alright
• Pressable captures (if you add it onPress handler) on taps outside ScrollView

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.

まず、iOS 上で https://github.com/birdofpreyru/rn-scroll-view-bug の必須再現手順を実行し、Pressable 内の ScrollView を繰り返しスクロールします。Pressable と ScrollView の iOS タッチ処理を追跡し、その後、Pressable が ScrollView の外側のタップを引き続き処理しながら、スクロールが確実に開始されることを確認します。
