Astro actions and avoid _action query param to avid brower resend form

I'm working with Astro and I love it, but there is something that I don't know if I'm doing in the right way or not.

I just created a form with a POST method and an action

<form method="POST" action={actions.user}>
  <input type="text" name="name" />
  <button type="submit"> Submit </button>
</form>

and an action like this

import type { APIContext } from 'astro';

import { defineAction, type ActionAccept } from 'astro:actions';
import { z } from 'astro:schema';

type InputType = z.infer<typeof inputSchema>;

const inputSchema = z.object({
  name: z.string().min(1),
});

export const server = {
  user: defineAction({
    accept: 'form' as ActionAccept,
    input: inputSchema,
    handler: async (input: InputType) => {
      const { name } = input;
      console.log('test!', name);
      return { status: 200 };
    },
  }),
};

It works very well, as expected, but the problem is that every time I submit the form, Astro adds a _action query param to the URL. If the user reloads the browser, it reruns the action, and I think it's not a good thing, so I would like to avoid it. I tried to redirect the user from the action or similar, but nothing worked, do you know how can avoid this behaviour?

Project with the code and example: https://stackblitz.com/edit/astro-actions-test?file=src%2Factions%2Findex.ts Demo: https://astroactionstest-lfcr--4321--5a421e5b.local-corp.webcontainer.io/

If you write the name phillip, you will get this URL: https://astroactionstest-lfcr--4321--5a421e5b.local-credentialless.webcontainer.io/?_action=phillip. According to the browser, if you reload, you will get this

And the action will run again, so, how can I avoid it?

Thanks in advance!
