Details

It would be good to measure how much slow reflow is biting us in the wild, and also measure that we're getting better over time. This is more important for interactive use cases (i.e., start measuring after page load is complete.) We need to define what "slow" means (e.g., >= 60ms?) and what interactive cases we want to catch (e.g., scrolling, mouse clicks, typing?)
