The EventTarget chain is determined before the Event is dispatched, as per DOM 2 Events. That has nothing to do with SVGElementInstance.correspondingUseElement however (correspondingUseElement is what the test is meant to test). The test does not in any way affect the Event object directly, or the way the event bubbles. The properties on a particular SVGElementInstance (which may be a target/currentTarget in the Event object) are subject to 'live' updates to match the current DOM tree.
