The environment settings object is effectively the context a piece of script is running under, for example, it contains the origin, responsible document, realm, global object and event loop for the current context. This effectively replaces ScriptExecutionContext, but it cannot be removed in this commit as EventTarget still depends on it. https://html.spec.whatwg.org/multipage/webappapis.html#environment-settings-object
