Remarks
This class stores detailed jank statistics for an individual UI widget. These statistics provide performance insights for specific UI widget states by correlating the number of "Janky frames" with the total frames rendered while the widget is in that state. This class can be used by library widgets to provide the system with more detailed information about where jank is happening for diagnostic purposes.
