Prerendering broken with ssr=false, prerender=true (and cloudflare) #12598
Description
Describe the bug
Somehow the following +layout.ts doesn't enable prerender completely, meaning it will generate the index.html but won't put the statically rendered content in it:
export const prerender = true;
export const ssr = false;<body data-sveltekit-preload-data="hover">
<div style="display: contents">
<script>
...
</script>
</div>
</body>However when using:
export const prerender = true;
export const ssr = true;The output is correctly prerendered:
<body data-sveltekit-preload-data="hover">
<div style="display: contents"><!--[--><!--[--><!----><!----><h1>Welcome to SvelteKit</h1> <p>Visit <a href="https://kit.svelte.dev">kit.svelte.dev</a> to read the documentation</p><!----><!----><!----><!--]--> <!--[!--><!--]--><!--]-->
<script>
...
</script>
</div>
</body>Maybe this is intended but then im not shure why.
This repro is using svelte v5 so that could also be an issue.
