React: How to catch `onInput` event with `InputEvent` arguments on `contentEditable` div?...

InputEvent.dataTransfer is always null...

Why 'input' event has `Event` type of event instead of `InputEvent`...

When does `getTargetRanges()` return more than one range?...

InputEvent.getTargetRanges() always empty?...

What are the valid strings for the typeArg argument of the InputEvent constructor?...
