Current Behavior

<script lang="ts">
  import type { FeaturedExpertFields } from '$houdini';
  import { fragment, graphql } from '$houdini';

  export let expert: FeaturedExpertFields;

  $: data = fragment(
    expert,
    graphql(`#graphql
      fragment FeaturedExpertFields on CoachProfile {
        id
        nam # Autocomplete and error reporting not working!
      }
    `)
  );
</script>

<a on:click={() => {}}>Hello world!</a>

Expected Behavior

<script lang="ts">
  import type { FeaturedExpertFields } from '$houdini';
  import { fragment, graphql } from '$houdini';

  export let expert: FeaturedExpertFields;

  $: data = fragment(
    expert,
    graphql(`#graphql
      fragment FeaturedExpertFields on CoachProfile {
        id
        nam # Autocomplete and error reporting here works perfectly!
      }
    `)
  );
</script>

<a>Hello world!</a>

Steps To Reproduce

As soon as the handler (any kind of handler, not just click) is added, LSP features stop working: 
 `on:click={() => {}}`

Environment

- LSP Server Version: latest
- OS: macOS 13.1
- LSP Client: vscode
