Description

Description

When the sectionList component calls the scrollToLocation method, the stickySectionHeader occasionally does not display.The stickySectionHeader only displays when I manually trigger scrolling in the sectionList.

Steps to reproduce
  1. install the application
  2. cd ReproducerApp and run npm ci
  3. npx react-native run-ios
  4. then wait for 3 seconds, the scrollToLocation method will be called

This issue does not always occur; it happens occasionally. You can try reloading several times.

Research direction

Start by running the mandatory reproducer at yandadaFreedom/RN-bug-repo, following its ReproducerApp setup and triggering SectionList.scrollToLocation after three seconds. Compare the automatic scroll with manual scrolling on iOS and trace the SectionList stickySectionHeader behavior; done means the header displays consistently after the programmatic scroll.
