Current behavior

Expected behavior

Images shouldn't be overalapping, I had to switch to FlatList from RN.

To Reproduce

Create a Stack Navigator with expo-router, and presentation set as modal. The animation from modal on iOS makes the FlashList items overlap 50% of the times. If i change presentation to card then issue disappears. To keep it as modal I had to switch to FlatList and issue is gone.

Platform:

• [X ] iOS
• Android

Environment

"@shopify/flash-list": "1.7.6",
"expo-router": "~5.1.3",
"react": "19.0.0",
"react-native": "0.79.5",
