btw currentScript can return null

[alex-kinokon]

document.currentScript is returning null | HTMLScriptElement | SVGScriptElement per https://html.spec.whatwg.org/multipage/dom.html#dom-document-currentscript

the definition has it:

interface Document extends Node, GlobalEventHandlers, NodeSelector, DocumentEvent, ParentNode, DocumentOrShadowRoot {
    readonly currentScript: HTMLScriptElement | SVGScriptElement;
}

please fix
