`jest-fake-timers` breaks `util.promisify(setTimeout)`

See original GitHub issue

🐛 Bug Report

Jest breaks util.promisify(setTimeout) functionality when using fake timers. When running code with jest-fake-timers it doesn’t have the field setTimeout[util.promisify.custom], even in jest-environment-node (jest-environment-jsdom correctly doesn’t have it).

(Updated description to refer to the specific jest-fake-timers problem)
