--- Comment #5 from Andrew Scheuermann <andrewscheuermann at gmail.com> ---
To clarify, the "Steps to reproduce" show a PerformanceObserver that is created with {type: 'paint', buffered: true}. The presence of the buffered parameter means that the PerformanceObserver callback should invoke with paint entries that occurred ~before~ the observer is added.

You can reproduce this buffered behavior on Chrome, Firefox, Opera, and Edge by copying in the code at any time after the initial paint occurs.


I've updated the bug description to "PerformanceObserver should work with {type: 'paint', buffered: true }"
