Describe the bug

The language server incorrectly reports "Cannot find name" error when using {@render ...} inside snippet definitions, even though the snippet function is properly defined under specific conditions.

Reproduction

<script module lang="ts">
</script>

<script lang="ts">
  function foo() { console.log("hello") }
</script>

{#snippet test()}
  {@render renderButton()}
{/snippet}

{#snippet renderButton()}
  <button type="button" onclick={foo}>test button</button>
{/snippet}

Expected behaviour

No "Cannot find name" error should be reported for properly defined snippet functions.

System Info

• OS: Windows 11
• IDE: VSCode (Ver. 1.96.3)
• Svelte for VS Code: 109.5.2

Which package is the issue about?

svelte-language-server

Additional Information, eg. Screenshots

I have verified this issue across multiple versions:

• The error is present in versions 109.5.2 and 109.5.0
• The error does not exist in version 109.4.0. The Expected behaviour screenshot was taken using this version.

The error can be eliminated by either:

• Removing the onclick={foo} handler
• Removing the <script module lang="ts"></script> tag

Additionally, {@render renderButton()} functions correctly when used outside of snippet definitions.
