redirect creates a blank page.

[LuckyMika]

Describe the bug

In my project, I want users that go to /account to be redirected to /account/profile. The first solution I came up with is simply putting a

goto("/account/profile")

and that worked, but even on local server you could still briefly see the /account page contents. I then turned to using the redirect function, because I didn't want to start hacking around trying to make it render the /account/profile page and change the URL. When I tried using redirect in a components script tag, it changed the URL but displayed an error page with "500 Internal Server Error". Then I tried using redirect in a +page.ts file, but that just produced the blank white page.

Reproduction

1. Create a SvelteKit app and create the folders src/account and src/account/profile
2. Create server.ts in src/account and +page.svelte in src/account/profile
3. Make a load function in server.ts that throws redirect:

   
   import { redirect } from "@sveltejs/kit"

export async function load() { throw redirect(300, "/account/profile") }

4. Add any element in `+page.ts`:
```html
<h1>This is an h1</h1>

5. Run npm run dev & visit the dev server at /account in the browser
6. Blank page!

Logs

No logs on either side.

annoyance

Additional Information

I used npm for this, not pnpm. I can work around it with the hack mentioned in the description, but if there is a better way/fix let me know.

300 is not a correct HTTP status code for an automatic redirect.
