Someone should show Lighthouse to Gmail team. Does not seem like there was any performance budget set for the new redesign.

Good video. As stated, there is a real problem with iframes, which execute on the main thread. Why can't they be executed in background ? For example, if you integrate the Google One Tap Sign In / Sign up, which is a exciting feature, it loads through an iframe, blocks your main thread and destroy your responsiveness so your Lighthouse metrics.

While Lighthouse help us to improve the quality of our websites, the performance results are always inaccurate and unstable, all the time, incognito mode or not. The recent inclusion of "Performance Insights" in Chrome are giving us better results in performance than Lighthouse.
