Horizontal FlashList header not reachable after scrolling in RTL mode

Bug Report

When using a horizontal FlashList with a ListHeaderComponent in RTL mode, the header becomes unreachable after scrolling to the end of the list. Swiping back toward the start never reveals the header.

Steps to Reproduce

1. Set I18nManager.forceRTL(true)
2. Create a horizontal FlashList with a ListHeaderComponent
3. Scroll to the end (swipe left-to-right in RTL)
4. Try to scroll back to the header (swipe right-to-left)
5. Header is never shown

Expected Behavior

The header should be reachable by scrolling back to the logical start of the list.

Environment

• flash-list: 2.3.0
• react-native: 0.84.1
• Platform: iOS 18
