Target attribute not supported on <form> with use:enhance

[McAndze]

Hi, thank you for this cool tool. I'd like to use it in a widget that's embedded in an iFrame. In this case, I want the redirect to target _top such that the top window container is what navigates when receiving the redirect.

I was unable to find anything regarding the expected behaviour here, so forgive me if this should be more of a feature request than a bug.

Description
When using use:enhance, the target attribute of the <form> is not respected. This makes the behaviour different to non-JS users.

If applicable, a MRE
I have modified the tutorial example a bit to throw a redirect and set a target="_blank" on the <form>. No matter what you set the target to, the redirect will be opened inside the preview. When removing use:enhance, the redirect opens in a new tab as expected.

I realize I could probably tap into something like onResult and achieve this behaviour, but it seems generally desirable to use the same behaviour as the non-enhanced redirect behaviour.

Hi, glad you like Superforms! Can you check if this is a more general SvelteKit issue by swapping the use:enhance for the SvelteKit built-in version?

Also, since Superforms 2 is available I don't have much time to add features to version 1, so please use this as a template instead: https://stackblitz.com/edit/superforms-2-testing?file=src%2Froutes%2F%2Bpage.server.ts,src%2Froutes%2F%2Bpage.svelte

Closing, as this seems to be a SvelteKit issue (as it doesn't work with the built-in enhance as well). An issue is opened here: sveltejs/kit#11931
