Event — preventDefault on non-cancelable has no effect

📖 Usage Example

const e = new Event('click', { bubbles: true, cancelable: true })
e.stopPropagation()  // prevents bubbling to parent elements

stopPropagation() prevents the event from bubbling up to ancestor elements.

Event.preventDefault — non-cancelable

Calling preventDefault() on a non-cancelable event is a no-op — defaultPrevented stays false.

Challenge: Verify that preventDefault() on a non-cancelable event does not change defaultPrevented.
