I get why they do it – and users probably prefer it – but this does feel like it kinda misses the point of CWV react.dev/blog/2025/10...

React uses heuristics to ensure throttling does not impact core web vitals and search ranking.

For example, if the total page load time is approaching 2.5s (which is the time considered “good” for LCP), React will stop batching and reveal content immediately so that the throttling is not the reason to miss the metric.
