So Element.prototype is in the variable scope chain of event handlers? Wow. Is 
this documented somewhere?

You mean other than in the spec? See http://www.whatwg.org/specs/web-apps/current-work/multipage/webappapis.html#getting-the-current-value-of-the-event-handler step 10.

Note that it's not Element.prototype that's in the scope chain but the element itself. It's just that the property lookup on the element will walk its proto chain.
