[Bug]: `URLSearchParams#get(k, v)` is not implemented and uses `URLSearchParams#get(k)` instead about jest

[SimenB]

That's because you're using jsdom@24 in your test, which is the newest version. If you install jsdom@20 (which is what ships with Jest) you can see the test failing in the same way with the builtin test runner.

jest-environment-jsdom@next (v30 alpha) ships with jsdom@22. You can setup a version with jsdom@24 using https://www.npmjs.com/package/@jest/environment-jsdom-abstract
