Describe the Bug

If you use dynamic importing with components, the styles don't load the first time. You need to edit something and save to see the changes.
This didn't happen with Astro 5
Also, you can see in the console that the Home page loads twice for some reason.

Additionaly, sometimes I saw the error [404] /@id/astro/runtime/client/dev-toolbar/astro_runtime_client_dev-toolbar_entrypoint__js.js.map when the page reloads in my local, but I wasn't able to reproduce it yet in the reproduction project. I'm not sure if it can be related to #15857, #15840

What's the expected result?

The styles to work fine after starting the dev server
