The below HTML/JavaScript is expected to output "object" for the line containing "typeof o". It returns "function" instead.
<!DOCTYPE html>
<script>
var o = document.createElement("object");
console.log(o);
console.log(Object.getPrototypeOf(o));
console.log(typeof o);
</script>

<https://tc39.github.io/ecma262/#sec-typeof-operator-runtime-semantics-evaluation> checks for [[Call]].
<http://heycam.github.io/webidl/#call> defines objects with legacy callers have [[Call]].
<https://html.spec.whatwg.org/multipage/#htmlobjectelement> defines that HTMLObjectElement has a legacy caller.
-> our behaviour is correct.
