🐛 Bug Report — URLSearchParam type reported by toString is object instead of URLSearchParam

[Phoenixmatrix]

I believe this is a regression that may have happened a while ago.

In Cloudflare functions (eg: In Pages), if you run toString.call(new URLSearchParams()), you get [object Object].

In Nodejs, or in Chrome, the result is [object URLSearchParams]

Some libraries depend on this behavior for runtime type checking where instanceOf might not be reliable.
I believe this used to work, as I stumbled on some library that had been tested in Cloudflare worker/pages in the past and got the expected result, but it no longer does (I cannot confirm this).

Issue reproed in a Cloudflare Pages project in a Function.
