[We will only be able to work on the issues that we can reproduce.]

[Please provide a self-contained example in a form of a snippet, archive or a repository.]

[Repro scenario can't be large or have external dependencies.]

Steps

• Make a fresh install of the SvelteKit with Typescript and Playwright support
• Add src/lib/foo.ts with exported foo function
• Add src/lib/baz.ts with exported baz function. The baz.ts should import and use foo function
• Import baz into tests/test.ts and use it inside of the test function call
• To be sure that it is not the same issue as [BUG] cannot see $lib with sveltekit2 #28781, apply the workaround

Expected

Tests are passed, "foo" is printed in the console.

Actual

Tests fails with this output

> playwright test

[WebServer] "confetti" is imported from external module "@neoconfetti/svelte" but never used in "src/routes/sverdle/+page.svelte".
