Changes
Closes #12252
Server Islands are not rendering as islands in .mdx files because server islands metadata is not added for JSX components in MDX files.
Even after adding server islands metadata, the issue persists because transform function in vite-plugin-server-islands.ts file runs before server metadata is added in rehype.ts file.
I found that vite-plugin-server-islands.ts is added last in create-vite.ts and has
enforce: 'post'
but still transform function is running before the server meta data is added.I am looking for feedback and guidance from Astro contributors on how to fix it.
