So the event is fired during a reflow... but the thing is that by the time the event fires the document in question has no script global object.

This doesn't seem like an unreachable situation while we null out script globals...

Still happens on trunk, following the steps in comment 0.

Which event fires during reflow?  Is that itself a violation of an invariant?  Are there other bugs covering that?

Comment 4

[Boris Zbarsky [:bzbarsky]]

I can't actually reproduce this locally at the moment...  So I don't know.

You can get the answer to your first question from the stack.  Given the stack, I could probably also answer your second question.
