Description Doran Moppert 2018-06-25 21:52:39 EDT

In the previous mitigations for Spectre, the resolution or precision of various methods was reduced to counteract the ability to measure measuring precise time intervals. In that work, `PerformanceNavigationTiming` was not adjusted but it was found that it could be used as a precision timer.
