Description

lib Update Request

Configuration Check

My compilation target is esnext and my lib is ["ESNext", "dom"].

Missing / Incorrect Definition

window.opener should not be typed as any. I might be missing something obvious, but this has already been reported and supposedly fixed at #42433 more than a year ago, but it still seems to be typed as any, both on my local version of Typescript (version 4.7.3) and at https://github.com/microsoft/TypeScript/blob/main/lib/lib.dom.d.ts#L17209

Contributor guide

Research direction
Locate the definition of window.opener in lib.dom.d.ts and change the type from any to WindowProxy | null.
