Just to make sure I understand, these EventHandlers are not in the spec, but
this patch keeps them to not change existing behavior?

Precisely, these were on Element.idl and I moved them here for higher
visibility, no observable change expected. The unprefixed ones won't be on
Element though, just on Document.
