ECMAScript's OrdinaryFunctionCreate has another new parameter

### What is the issue with the HTML Standard?

[OrdinaryFunctionCreate](https://tc39.es/ecma262/#sec-ordinaryfunctioncreate) now has `env` and `privateEnv` arguments, but is called with a `scope` argument instead in [_getting the current value of the event handler_](https://html.spec.whatwg.org/multipage/webappapis.html#getting-the-current-value-of-the-event-handler).
