What issue should you be aware of when implementing code splitting in a server-side rendered application?
Hydration mismatches between server and client bundles are a critical consideration in SSR applications with code splitting because: 1) Server and client must agree on which chunks are needed for initial render, 2) Mismatches can cause content flashing or errors during hydration, 3) Loading states need to be handled consistently between server and client, 4) Bundle configuration must ensure proper alignment of server and client code. This requires careful configuration of your bundler and proper implementation of loading states and error boundaries to handle potential mismatches gracefully.
