Description

navigator.scheduling.isInputPending is shipping by default in current Chrome stable (m87). Without user input, any page using isInputPending has a strong reason to believe yielding during long tasks won't improve user experience so it could keep on chugging instead.

This may have a large impact on any metric looking at long tasks (TBT, TTI) compared to what a real user would experience when loading the same page.
