HttpStatusCode not working

is it just me or

<HttpStatusCode/>

<HttpStatusCode/>

not working?
here's the code I'm trying for the route

import { HttpStatusCode } from "@solidjs/start"

export default () => <>
    <HttpStatusCode code={404}/>
    <h1>404</h1>
</>

import { HttpStatusCode } from "@solidjs/start"

export default () => <>
    <HttpStatusCode code={404}/>
    <h1>404</h1>
</>

it seems to just have no effect, I still get

in the browser
