Four elements match the "potentially delay the load event" check in the spec: `<embed>`, `<frame>`, `<iframe>`, and `<object>`. These four are the same set of elements that are NavigableContainers (or will be once we implement them) so let's put this logic there. Note that other things can delay the load event, this is just the name the spec gives to this particular behaviour.
