TypeScript error thrown when exported snippets reference a type of a script element

Describe the bug

When exporting snippets referencing the type of a value from the regular <script> block, the TypeScript error:

Cannot find name '<exportedSnippetName>'. (ts 2304)

is thrown instead of the expected error:

An exported snippet can only reference things declared in a `<script module>`, or other exportable snippets
https://svelte.dev/e/snippet_invalid_export

Note: I don't know if type references should error at all; it's not a blocking issue as actual object references can be, if type references are ever a problem. Nonetheless, it should emit the same error message as object references instead of this generic TS error.

Side idea: if possible, problematic object references within the snippet could be underlined as well, allowing for instantaneous identification of the precise cause; this would be awesome!
