HTMLDialogElement: cancel event

The cancel event fires on a <dialog> when the user instructs the browser that they wish to dismiss the current open dialog. For example, the browser might fire this event when the user presses the Esc key or clicks a "Close dialog" button which is part of the browser's UI.
