Answer
React replays events fired before hydration finishes, ensuring consistent event processing.
Quick Answer
React uses a root-level event listener (attached to the container div) for all synthetic events. In concurrent mode, events are processed after the current render commits, not during. React stores the event, commits the render, then dispatches it. This guarantees event handlers always see a fully consistent, committed DOM state.
