Could you change this to be somewhat more readable?

: Event(type, true /* canBubble */, true /* cancelable */)

Why are both of these true? Where would it bubble to, and what happens when it
gets cancelled?

[Michael van Ouwerkerk, 2014/05/21 17:06:42]

You're right, these should probably not bubble or be cancelable.
