Details

Both Blink and WebKit enqueue dispatching events between beforeinput event and input event. We should follow it because:

  • Web apps get more similar behavior as Blink/WebKit than now
  • beforeinput allows web apps to catch to change the DOM tree without legacy mutation events
  • It makes editor code simpler
  • It might improve the performance of editor

Of course, even if we don't dispatch beforeinput event for conforming to the spec, we should enqueue them until dispatching input event.

Marking this as a blocker of crash bugs and assertion failure bugs which are caused by event listeners which run while editor handles something.
