`redirect()` inside Server Actions doesn't work with the same domain

Link to the code that reproduces this issue

https://github.com/steven-tey/server-action-redirect-bug

To Reproduce

Go to https://server-action-redirect-bug.vercel.app/, type in any password and click "Log In". You'll see the URL change to have the ?pw= query param:

However, this is incorrect since we have a middleware that says if there's a pw query param, redirect to https://dub.co. Refreshing the page fixes this.

Current vs. Expected behavior

Current: redirect() does a "soft" redirect and doesn't actually refresh the router Expected: redirect() triggers a router refresh and redirects to the final URL (https://dub.co) (as per the docs)
