The MessagePort one in particular is required by Cloudflare Turnstile, as the method it takes to run JS in a worker is to `eval` the contents of `MessageEvent.data`. However, it will only do this if `MessageEvent.isTrusted` is true, `MessageEvent.origin` is the empty string and `MessageEvent.source` is `null`. The Window version is a quick fix whilst in the vicinity, as its MessageEvent should also be trusted.
