Description

Bug Report

As the title says, the URL interface (#3753) should be part of the Window object: window.URL. Please look at https://developer.mozilla.org/fr/docs/Web/API/URL .

window url, url, new url, createObjectURL, revokeObjectURL

🕗 Version & Regression Information

I'm using TypeScript 4.2.4.

🙁 Actual behavior

window.URL is not defined.

🙂 Expected behavior

window.URL should refer to the URL interface you added on the issue #3753:

URL: {
    prototype: URL;
    new(url: string, base?: string | URL): URL;
    createObjectURL(object: any): string;
    revokeObjectURL(url: string): void;
};

Contributor guide

Research direction
Look at the existing lib.dom.d.ts file to see how other Web API interfaces (e.g., Document, Location) are added to the Window interface. Check the referenced issue #3753 for context on the URL interface definition. Then, add the URL interface to the Window type in the appropriate location, ensuring it matches the expected shape from MDN.
