Remote form's automatic reset should clear touched state, etc.

[hyunbinseo]

Describe the bug

SvelteKit's "automatic form reset after remote form submission" should do a full reset including touched states.

Existing issues request APIs to do this:

• Add a clear and reset methods to the form remote function #14210
• remote form: resetting form does not clear validation errors and does not reset touched state #14754

But I really hope this becomes the SvelteKit's default:

• feat: Reset form programmatically #14779

Currently, using oninput or onchange for validation shows incorrect messages in consecutive form submissions.

Reproduction

For some reason, I can only reproduce this in Firefox. All password manager extensions were disabled.

1. Focus the email input
2. Enter a valid value and press Enter to submit
3. The form is automatically reset (reference)
4. Click outside the input to trigger onchange
5. The following validation error is shown:

Invalid email: Received ""

<script lang="ts">
  import { PublicSchema } from './form';
  import { submitEmail } from './form.remote';
</script>

<form
  {...submitEmail.preflight(PublicSchema)}
  onchange={() => submitEmail.validate({ preflightOnly: true })}
>
  <label>
    <span>Email</span>
    <input {...submitEmail.fields.email.as('email')} />
  </label>
  <ul>
    {#each submitEmail.fields.email.issues() as issue}
      <li>{issue.message}</li>
    {/each}
  </ul>
  <button>Submit</button>
</form>
