Describe the Bug

As I mentioned here : withastro/adapters#454 (comment)

Image does not load, when Image component are used in Server Islands (server:defer) enabled component.

Minimal reproducible example here :

and deployed to:
https://f844fa98.astro-server-islands-3dq.pages.dev/

This is working in Astro v4 with CF Adapter v11.

What's the expected result?

Image should load.
