This CL adds use counters to analyze the impact of implementing the change proposed in [1]. Following counters are added: 1. kEditContextUpdateTextRangePrecedesOrOverlapsSelection: Tracks when updateText is called and the update range precedes or overlaps the selection. 2. kEditContextUpdateTextRangePrecedesCompositionRange: Tracks when updateText is called and the update range precedes the composition range during an active composition. 3. kEditContextUpdateTextRangeOverlapsCompositionRange: Tracks when updateText is called and the update range overlaps with the composition range during an active composition. 4. kEditContextUpdateSelectionDuringActiveComposition: Tracks when updateSelection is called during an active composition. [1] w3c/edit-context#115 These counters will help us understand how frequently these behaviors occur before making changes to the spec implementation.
