What steps can reproduce the bug?

const app = new Elysia()
    // .use(jwtPlugin)
    .group(
        '/ws',
        {
            query: t.Object({
                token: t.String(),
            }),
        },
        (app) =>
            app
                .derive({ as: 'scoped' }, async ({ jwt, query: { token }, set }) => {
                    const tokenValues = await jwt.verify(token);
                    if (!tokenValues || !tokenValues.user) {
                        set.status = 401;
                        return buildErrorResponse('Unauthorized');
                    }
                    const user = JSON.parse(tokenValues.user as string);
                    console.log('derive user', user);
                    return {
                        user,
                    };
                })
                .ws('/', {
                    open: async ({ id, data: { user } }) => {
                        //                    ^ TS2339: Property user does not exist on type xxx
                        console.log('opened');

                        console.log('opened user', user); // <- user object actually exists. Only type is no getting inferred
                    },
                }),
    );

If derive is not async, the type is inferred in WS properly, but with async it does not show up

What is the expected behavior?

Async derived types are correctly inferred

What do you see instead?
