Make defaultPrevented effectful

Is this because its value will change after preventDefault occurs elsewhere?

[fghibellini]

element.addEventListener('click', evt => {
  console.log(evt.defaultPrevented);
  evt.preventDefault();
  console.log(evt.defaultPrevented);
})

// upon click outputs:

> false
> true

Based on the above behavior I would suppose defaultPrevented cannot be effectless.
Am I missing something?

No, you're absolutely right - I was just checking I understood the motivation for the change. Thanks!

I'll merge this soon, it's a breaking change, so will need a bit of figuring out. I'll see if I can find anything else that needs breaking at the same time.
