Redirect browser path not changing when manually editing it

[haleksandre]

I'm currently encountering a weird issue.

On initial load/hard refresh, the app redirects the user from / to the sign-in page /signin. So far so good, the hook runs, the server-side/client-side load runs & the browser indicates the correct path /signin. If I try my sign in everything works as expected.

<form
  method="POST"
  action="?/signin"
>
  <!-- form -->
</form>

the form correctly calls the action signin within the /signin/+page.server.ts file.

When manually changing the path from the address bar from /signin to /. The redirect happens since I see the sign-in page but somehow for some reason the path in the browser address bar remains /. Then when I try the above form I get a 405 error. 405 POST method not allowed. No actions exist for this page.

I'm guessing since the browser URI is set to / & the action is action="?/signin" SvelteKit looks for the action within /+page.server.ts file & not /signin/+page.server.ts even though the page shown is within /signin.

I can, of course, work around that by changing the form's action to an absolute path like so action="/signin?/signin" but Im wondering why when I manually change the path in the browser's address bar SvelteKit load the right page but the path in the address bar doesn't change & then this problem, & potentially other, occurs?

Upon further investigation, looks like the weird path issue isn't with SvelteKit but Vite PWA plugin which doesn't trigger server-side requests on manual URI requests so the server-side hook & load don't run when manually going back to a path that redirected you, in this case / to /signin.
