Sticky headers in FlatList/ScrollView become non-touchable after upgrading to 0.79.2

Description

After upgrading to React Native version 0.79.2, sticky header indices (stickyHeaderIndices) in both FlatList and ScrollView components become non-responsive to touch events. The content renders correctly but fails to respond to any user interaction (taps, presses, etc.).

Expected Behavior:
Sticky headers should remain touchable/interactive as in previous versions (e.g., 0.79.1 or earlier), allowing users to interact with buttons, links, or other touchable elements within them.

Observed Behavior:
Sticky headers are visually rendered but ignore all touch events. This breaks functionality for interactive elements (e.g., buttons, checkboxes) within sticky sections.

Reproduction Steps:
Create a FlatList or ScrollView with stickyHeaderIndices set.
Add touchable elements (e.g., TouchableOpacity, Button) inside the sticky header.
Upgrade to RN 0.79.2.
Observe that touch events on sticky headers no longer work.

<ScrollView
style={{ flex: 1 }}
ref={scrollViewRef}
stickyHeaderIndices={[1]}
onScroll={handleScroll}
scrollEventThrottle={16}
nestedScrollEnabled>
.....

Environment:
React Native: 0.79.2
Platform: Android (observed)
Device: All Real devices

Steps to reproduce

Create a FlatList or ScrollView with stickyHeaderIndices set.
Add touchable elements (e.g., TouchableOpacity, Button) inside the sticky header.
Upgrade to RN 0.79.2.
Observe that touch events on sticky headers no longer work.

No response

index.js にある必須の reproducer から始め、React Native 0.79.2 を使用して Android で実行し、0.79.1 と動作を比較します。FlatList と ScrollView stickyHeaderIndices のインタラクション経路を追跡します。Android で sticky header 内のタッチ可能な要素が再び反応するようになれば完了です。
