This fix looks good. But I'm wondering if it is ever correct to fire multiple load events. If not, would it be better to fix that underlying bug instead of this?

From a quick reading of the spec, it looks like it is valid to fire load twice. Any time the parser reaches the end, it's supposed to fire load. document.open() is supposed to create a new parser, so it seems valid to hit load repeatedly.

I don't see any of the changed code on the stack and it seems unrelated. I would suspect another change or just flakiness.
