> > When the user agent changes the element's value on behalf of the user
> > (e.g. as part of a form prefilling feature), the user agent must follow
> > these steps:
> > 1. If the input event applies, queue a task to fire a simple event
> > that bubbles named input at the input element.
> > 2. If the change event applies, queue a task to fire a simple event
> > that bubbles named change at the input element.
