The lookup chain is first document then window, with no elements anywhere, right?
The lookup order is the element the on* attribute is on, then the element's form if it's a form control (more or less; details are in the spec), then the document, then the window. There are also some additional complications in terms of time-invariance of the lookup chain, etc, which most browsers agree on but a few do not.
If this is a recurring problem
It is.
could we consider implementing magic so that new methods on Document (or Node) that might cause problems are ignored in on* unless you prefix with "document."?
We could consider it; it would require that what goes on the scope chain of on* even handlers is some sort of proxy instead of the actual element/form/document/etc, I think... That might work, though. Would somewhat hurt performance for whatever code is inside the on* attribute itself (not including functions it calls), but that's usually not that much code, and already has a certain amount of overhead for the C++ to JS transition. Maybe this is the way to go.
