Exception and stack trace are swallowed when an event handler throws

[zoechi]

I had a bug in my

void onClick(dom.MouseEvent e) {
   var elm;
   print(elm.innerHtml);
}

<ul  ng-click="cmp.onClick($event)">

And I get this stack trace

Undefined function onClick

This way it's hard to find the cause.
