Summary: See https://github.com/react-native-community/discussions-and-proposals/pull/335 for extra context. A VirtualizedList may have sticky headers, forwarded on to ScrollView. These sticky headers are exempt from virtualization once realized for the first time. This change documents the behavior of keeping sticky header cells realized after scrolling away. This scenario performs the same behavior as creating an internal "realization window" for sticky headers with a single cell window size. Generalizing the concept of realization windows should be shaped to support the existing sticky header scenario. ## Changelog <!-- Help reviewers and the release process by writing your own changelog entry.
