Maximum call stack size exceeded on accessing outerHTML #130

Closed Sembiance closed 1 year ago

Sembiance commented 1 year ago

When running deno_dom@v0.1.36-alpha/deno-dom-wasm.ts with deno 1.28.1 and loading the attached test.html.zip file and then attempting to access the .outerHTML property of the <html> tag with with this code:

import { DOMParser, Element } from "https://deno.land/x/deno_dom@v0.1.36-alpha/deno-dom-wasm.ts";

const doc = new DOMParser().parseFromString(await Deno.readTextFile("test.html"), "text/html");
const outerHTML = doc.querySelector("html").outerHTML;

causes this error:

error: Uncaught (in promise) RangeError: Maximum call stack size exceeded
