[🐞] Qwik 1.9.0 holds onto searchParams when redirecting from a server action

[brandonpittman]

Which component is affected?

Qwik City (routing)

Describe the bug

Through 1.8.0, our app would successfully redirect from server actions to some URL like /profile from the front page of the app. The front page takes an ?id=XXX param to get some data and then after tapping a consent button, it runs an action, saves data to a cookie and throws a redirect.

It used to drop the search params when redirecting. Since 1.9.0, it holds onto the search params.

Seems related to this:

But if this is what the team thinks should be the correct behavior, how can I drop the searchParams?

@brandonpittman can you provide a repro so we're talking about the same things? I thought that change was to provide search parameters when calling actions?

@wmertens

The Stackblitz link above shows this behavior:

If you submit a form from a page with searchParams and redirect in the action, the page you get redirected to has the previous page’s searchParams even though the redirect was to a route with no searchParams.

This only started with 1.9.0.

Here's a recording showing the problem (includes audio).

@wmertens Just for completeness, here's another Stackblitz (with recording) pinned at 1.8.0 where redirects don't hold onto the submitting page's searchParams.

Pretty sure this is what broke things:

Another problem is that if you redirect to a URL with searchParams, Qwik drops the params in the URL you try to redirect to.

I created a PR. Can someone take a look at it, please?
