- Introduce IntersectionObserver to detect scroll events for reaching the top and bottom of the message list. - Add new props for loading states and viewport management, including `loadingNewer`, `centerOnMessageId`, and `preserveViewportOnPrepend`. - Implement logic to emit events when the top or bottom of the message list is reached, allowing for dynamic loading of messages. - Refactor message loading logic to support windowed message display based on read anchors and user interactions. - Update unit tests to cover new scrolling behavior and viewport preservation features.
12 tasks
- Document changes to the chat timeline, including a bounded initial message window to improve loading experience. - Note the transition from button-based pagination to bidirectional infinite scroll for chat history. - Highlight the new initial message viewport behavior, centering around the user's last-read event when applicable.
