AFAICT this is working correctly as per the specification:
https://html.spec.whatwg.org/multipage/window-object.html#named-access-on-the-window-object

Since there can't be a variable that has a name beginning with a number, '0' is treated as a reference to a DOM element, hence 'undefined' is returned as there is no such element in the document.
