VSCode suggestions are too broad with Svelte extension

[bitkidd]

Describe the bug

For some reason Svelte to VSCode extension does not provide optimal TS experience in terms of suggestions, sometimes I get too many of them, sometimes none. I narrowed down the issue to round braces, so if some value is inside of them, suggestions do not work, if not, work okay.

Reproduction

Here suggestions do not work for me.

<script lang="ts">
  const someFunction = (input: string) => input

  export let data: { title: string; excerpt?: string } | null = null
</script>

{#if data}
  <h1>{someFunction(data.title)}</h1> <!-- Here suggestions after . do not work -->
  <p>{data.excerpt}</p>
{/if}

Expected behaviour

Suggestions that are strictly tied to the data type provided in script tag.

System Info
