CORS behavior not aligning with documentation

[ArkenV]

What version of Elysia is running?

Bun: 1.0.18, Elysia: Elysia --revision fails but it's a fresh installation as of 12/12/2024

What platform is your computer?

Darwin 23.5.0 arm64 arm

What steps can reproduce the bug?

import { Elysia } from "elysia";
import { cors } from "@elysiajs/cors";

const app = new Elysia()
  .use(cors({ origin: 'localhost:4200' }))
  .post("/test", req => req.body)
  .listen(3000);

What is the expected behavior?

I expected only requests coming from localhost:4200 to be allowed.

What do you see instead?

For some reason, the origin must be passed in as an array. ['localhost:4200'] works, but the other types (regex, true) listed in the documentation do not. I understand true would allow all traffic and wouldn't be suitable for this purpose anyway, but I just want to point out that this also isn't functioning.

Additional information

No response

Have you try removing the node_modules and bun.lockb and try again yet?

It was a brand new project specifically for illustrating this bug
