Duplicate css bundles (different name) in build assets

[skiv71]

Describe the bug

Basic sveltekit project, with config for an SPA and a +layout.svelte file for common css dependancy across different routes.

Reproduction

1/. create a sveltekit app

2/. create a +layout.js with...

3/. create another route with a +page.svelte (and some content)

4/. create a +layout.svelte in src/routes with content: -

Can't be good for distributing an SPA?
