What steps can reproduce the bug?

It is breaking cors plugin.

Something like this:

import { Elysia, sse, status } from 'elysia'

const app = new Elysia()
    .get('/fail', async function* ({ set }) {
        set.headers["access-control-allow-origin"] = "*";
        throw status(500);
    })
    .get('/work', async function* ({ set }) {
        set.headers["access-control-allow-origin"] = "*";
        return status(500); // <- returns
    })
    .listen(3000)

import { app } from '../server'
import { treaty } from '@elysiajs/eden'

const api = treaty(app);

(async () => {
    const fail = await api.fail.get();
    console.log("fail.headers", fail.headers);

    const work = await api.work.get();
    console.log("work.headers", work.headers);
})();

What is the expected behavior?

headers to be sent, cors plugin to work.

What do you see instead?

headers not sent.
