beforetoggle and toggle should be ToggleEvent not Event

[johanrd]

I'd expect beforetoggle and toggle events to have event.newState and event.oldState from ToggleEvent (which Inherits from Event.)

interface GlobalEventHandlersEventMap {
-"beforetoggle": Event;
+"beforetoggle": ToggleEvent;
-"toggle": Event;
+"toggle": ToggleEvent;

/** [MDN Reference](https://developer.mozilla.org/docs/Web/API/HTMLElement/beforetoggle_event) */
-declare var onbeforetoggle: ((this: Window, ev: Event) => any) | null;
+declare var onbeforetoggle: ((this: Window, ev: ToggleEvent) => any) | null;

/** [MDN Reference](https://developer.mozilla.org/docs/Web/API/HTMLElement/toggle_event) */
-declare var ontoggle: ((this: Window, ev: Event) => any) | null;
+declare var ontoggle: ((this: Window, ev: ToggleEvent) => any) | null;

interface GlobalEventHandlers {
/** [MDN Reference](https://developer.mozilla.org/docs/Web/API/HTMLElement/beforetoggle_event) */
-    onbeforetoggle: ((this: GlobalEventHandlers, ev: Event) => any) | null;
+    onbeforetoggle: ((this: GlobalEventHandlers, ev: ToggleEvent) => any) | null;

/** [MDN Reference](https://developer.mozilla.org/docs/Web/API/HTMLElement/toggle_event) */
-    ontoggle: ((this: GlobalEventHandlers, ev: Event) => any) | null;
+    ontoggle: ((this: GlobalEventHandlers, ev: ToggleEvent) => any) | null;
