[svelte] Can't get snippets to work in script part of .svelte file.

[ItaloCunhaBueno]

Can someone explain to me what am I doing wrong here? Tried to add the following snippet to work in the script part of svelte:

{
  "Import Form": {
    "prefix": "cni-x-form",
    "body": ["import * as Form from \"$lib/components/ui/form/index.js\"", ""],
    "description": "https://next.shadcn-svelte.com/docs/components/form.html"
  }
}

I tried this code in svelte.json, javascript.json and typescript.json snippets, none of them worked (restarted zed in each save). Snippets in svelte.json are working correctly for the body part of .svelte file, but not for the script part.
