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.
