Vite SSR build warning

[NeroBlackstone]

Describe the bug

Use sv cli to create a sveltekit project, upgrade all dependencies to the latest version, and execute bun run build. The following warning appears:

Export "setContext" of module "node_modules/svelte/src/internal/server/context.js" was reexported through module "node_modules/svelte/src/index-server.js" while both modules are dependencies of each other and will end up in different chunks by current Rollup settings. This scenario is not well supported at the moment as it will produce a circular dependency between chunks and will likely lead to broken execution order.
Either change the import in ".svelte-kit/generated/root.svelte" to point directly to the exporting module or reconfigure "output.manualChunks" to ensure these modules end up in the same chunk.
Export "getContext" of module "node_modules/svelte/src/internal/server/context.js" was reexported through module "node_modules/svelte/src/index-server.js" while both modules are dependencies of each other and will end up in different chunks by current Rollup settings. This scenario is not well supported at the moment as it will produce a circular dependency between chunks and will likely lead to broken execution order.
Either change the import in "node_modules/@sveltejs/kit/src/runtime/app/state/server.js" to point directly to the exporting module or reconfigure "output.manualChunks" to ensure these modules end up in the same chunk.

same warning when I upgraded from 5.31.1 to 5.32.1

Maybe it is a good idea to have a simple smoke test that just runs a build on the demo app to discover something like this before a release is made?
