Perhaps.

> The resize event is supposed to tell the JavaScript that the user resized the page or frame, not that the browser resized the frame programmatically.

I am not sure that is correct. With frame flattening disabled, we always fire the resize event when an iframe’s size changes, regardless of the reason (which is typically layout of the containing document). This makes sense to me, because whatever the event handler does to adapt the document to the new size most likely needs to be done regardless of how the frame was resized.

I think the right fix for this should be along the lines of making the post-layout-task-deferral mechanism act on a document scope instead of on a single frame scope.
