Section sticky header in wrong place after list header change until scroll

Description

I migrating to the New Architecture.
I have component which worked fine 7 years on the "old architecture".
It uses Animated.SectionList and can hide content in ListHeaderComponent.
In the New architecture on ListHeaderComponent change: section header (renderSectionHeader) goes to the wrong place until manually scroll a little.

Steps to reproduce

1. Clone and run https://github.com/Bardiamist/diff/tree/section-list-header

2. Scroll util red header will stick

3. Press Hide top content after 1 sec button

4. Wait 1 second
   Expected result: red header should be in same place

5. Scroll a little

6. Press Show content after 1 sec button

7. Wait 1 second
   Expected result: red header should be in same place

Screenshots and Videos

Works with problem on the New Architecture:

https://github.com/user-attachments/assets/ceef7a7d-3e8e-49c9-83ba-2c402c8ce269

Worked as expected on the "old architecture":

Ejecuta en iOS el reproductor vinculado section-list-header con la New Architecture habilitada y, a continuación, inspecciona el comportamiento de Animated.SectionList y renderSectionHeader cuando el contenido de ListHeaderComponent está oculto o visible. Se considera terminado cuando el encabezado de sección rojo permanece en la misma posición después de ambos cambios sin requerir un desplazamiento manual.
