Describe the Bug

When developing the app locally everything works smoothly (because we are using nodejs for dev), but when we try to build the app without any changes it throws error

16:30:18 ▶ src/pages/index.astro
16:30:18 └─ /index.htmldocument is not defined
Hint:
Browser APIs are not available on the server.

If the code is in a framework component, try to access these objects after rendering using lifecycle methods or use a `client:only` directive to make the component exclusively run on the client.

See https://docs.astro.build/en/guides/troubleshooting/#document-or-window-is-not-defined for more information.

this is when we pass any children to svelte component and try to render the children.

I have tested with other adapters (deno and node) things works expected, children passed are rendered and build is completed.

What's the expected result?

It should render the passed children in SSR and build should complete
