leakRef?  That doesn't seem right.  Is this a memory leak?

Maybe we need to store a RefPtr to the ResourceProgressEvent in a local
variable?

[dmichael (off chromium), 2013/05/20 21:11:25]

WebDOMEvent takes a ownership of the reference. I added a new PassRefPtr
overload of WebDOMEvent::assign() to make it clearer.
