`data-sveltekit-keepfocus` does not work on POST forms

UPDATE: As explained by @s3812497 - I was confused and missed the info in the dosc, that this only works for GET forms, this would be a feature request for POST forms then as well.

There were two tickets related to this: https://github.com/sveltejs/kit/issues/7895 and https://github.com/sveltejs/kit/pull/9019 with the actual implementation.

The documentation confirms that we should be able to use data-sveltekit-keepfocus on a <form> element not to loose focus after the form is being submitted.

This seem not to work for me. Nor for forms with use:enhance, neither for those without. I've created a simple reproduction code: https://stackblitz.com/edit/sveltejs-kit-template-default-du58bc?file=src%2Froutes%2F%2Bpage.svelte Either that, or I don't fully understand how should it work from the docs.

Reproduction

1. Create a POST form and make it use:enhance
2. Add data-sveltekit-keepfocus attribute to it
3. Submit the form on:input

or use https://stackblitz.com/edit/sveltejs-kit-template-default-du58bc?file=src%2Froutes%2F%2Bpage.svelte

Severity

serious, but I can work around it

Start with the linked StackBlitz reproduction, especially src/routes/+page.svelte, and read the data-sveltekit-keepfocus documentation alongside issues #7895 and pull request #9019. Compare the documented GET-form behavior with POST forms using use:enhance and without it. Done means the requested focus-preservation behavior is defined and verified for POST submission.
