Can you help me understand why you need to know this event when text is not finalized?

For localization support when languages like Japanese or chinese are selected as system and browser language, drop down suggestions are showing up in editor. Once such suggestion is selected from drop down, which is finalized text, compositionEnd event is triggered but not input event.
