Basic info:
Since I migrated for the new version jsdom, looks like I can't delete window.onpagehide since is a property of his prototype.
- Node.js version: v8.9.4
- jsdom version: 11.6.2
Minimal reproduction case
const jsdom = require("jsdom");
const { JSDOM } = jsdom;
const { window } = new JSDOM(`<!DOCTYPE html><p>Hello world</p>`);
console.log(Object.getOwnPropertyDescriptor(window, "onpagehide")); // undefined
console.log("before", window.onpagehide); // null
console.log(delete window.onpagehide); // true
console.log("after", window.onpagehide); // nullHow does similar code behave in browsers?
