Hmm. That documentation doesn't really help. What are the arguments that
are passed to onerror? Is it an "event" object as normal? Or is onerror
not a DOM-like event but just a function pointer? Can you addEventListener
the error event, or is it only accessible from window.onerror as a
callback? If it's a normal DOM event, what does its interface look like?
I tried looking up this information on MSDN and in the Mozilla sources but
came up mostly empty.
