研究方向
Begin by examining the provided Codesandbox reproduction to understand the interaction between InfiniteScroll with replace prop inside a Grid. Look into the InfiniteScroll component source code in the Grommet repository, focusing on scroll position handling and the replace logic. Then investigate the Grid component's layout behavior to identify why items fail to render and scroll jumps occur.
