Svelte 5 field error validation does not trigger after a valid submission

[ArsalaanAnsariDeveloper]

Describe the bug

It seems that the submission behavior for the final component on https://next.shadcn-svelte.com/docs/components/form is a little erratic. If you look at the video, it correctly shows the field errors and toast message on the first submission with an empty username. However, after subsequent invalid submissions, it stops working.

The Svelte 4 example https://www.shadcn-svelte.com/docs/components/form always shows field errors on invalid submits and always shows the toast message, which I think is the ideal behavior. I am experiencing this behavior in my personal project as well.

Svelte 5 erratic behavior:

Svelte.5.Erratic.Behavior.mov

Svelte 4 ideal behavior:

Svelte.4.Ideal.Behavior.mov

Reproduction

Last component on https://next.shadcn-svelte.com/docs/components/form

Hey I was able to track down the issue! Seems to be something that was an issue on the svelte-kit side:

ciscoheat/sveltekit-superforms#536
sveltejs/kit#13205

Upgrading to 2.15.2 seems to do the trick.

"@sveltejs/kit": "^2.15.2",

Awesome to hear!

Will close this then!
