staticPlugin's prefix: '/' breaks elysia's mount()

[yuniruyuni]

What happen?

When you are using staticPlugin({prefix: '/'}) with mount() method,
Your fetch function faces req.url argument will rewrited as / all times.

Reproduction code

reproduction.ts

import { Elysia } from 'elysia';
import { staticPlugin } from "@elysiajs/static";

const app = new Elysia();

app.mount("/test/", async (req) =>{
        console.log(req.url);
        return new Response("test");
    });

app.use(staticPlugin({ prefix: "/" }));

export default {
    port: 3000,
    fetch: app.fetch,
};

run bun run reproduction.ts
and access http://localhost:3000/test/hogehoge.js or http://localhost:3000/test/fugafuga.png something so on,
then you will see the output is http://localhost:3000/ instead of expected http://localhost:3000/hogehoge.js or http://localhost:3000/fugafuga.png.

Environment

• Linux 6.9.3-3
