What steps can reproduce the bug?

• create custom JSX Component

function MyComponent() {
  return <></>;
}

and the app crash.

What is the expected behavior?

should render Fragment without import

What do you see instead?

Additional information

if you import import { Fragment } from "hono/jsx/jsx-runtime"; it works, but IDE not report any info that something is wrong
