OK, I hadn't considered that moving this to Element would imply the
content attributes being reflected for all namespaces. Even though
Blink has the IDL attributes on Element, it looks like the reflection
with the content attributes only works for HTMLElement and SVGElement.
In other words, "whatever Blink does" doesn't look like something
worth standardizing.

Erik, does going with "SVGElement implements GlobalEventHandlers"
(like Gecko) seems like a way forward for the SVG spec?
