--- Comment #5 from Karl Dubost <karlcow at apple.com> ---
As of today, the current spec specifies the order of the event in 
https://w3c.github.io/uievents/#events-composition-input-events


5.7.6. Input Events During Composition

During the composition session, the compositionupdate MUST be dispatched after the beforeinput is sent, but before the input event is sent.

Event Type      Notes
1       beforeinput     
2       compositionupdate       
                           Any DOM updates occur at this point.
3       input   

Note: Most IMEs do not support canceling updates during a composition session.

The beforeinput and input events are sent along with the compositionupdate event whenever the DOM is updated as part of the composition. Since there are no DOM updates associated with the compositionend event, beforeinput and input events should not be sent at that time.

Event Type      Notes
1       beforeinput        Canceling this will prevent the DOM update and the input event.
2       compositionupdate       
                           Any DOM updates occur at this point.
3       input              Sent only if the DOM was updated.
4       compositionend
