Why don't you use PassRefPtrWillBeRawPtr in WebDOMEvent in this patch?

[haraken, 2014/02/28 01:10:03]

WebDOMEvent has its own hierarchy, so using PassRefPtrWillBeRawPtr in
WebDOMEvent increases the patch size. So I want to do that in a separate CL.

It makes sense.  lgtm

+    WebDOMEvent event = PassRefPtr<Event>(frame->frame()->document()->createEvent("CustomEvent", IGNORE_EXCEPTION));
     WebDOMCustomEvent customEvent = event.to<WebDOMCustomEvent>();
 
     v8::Isolate* isolate = toIsolate(frame->frame());
