Describe the Bug

I have some import.meta.env in MDX's code blocks and don't want them to be converted. (Just display import.meta.env.XXXXX)

In dev environment, the output is doing well.

However, import.meta.env.SITE becomes undefined (or the url I defined in astro.config.mjs); import.meta.env.PUBLIC_HOSTNAME becomes (Object.assign(import.meta.env,{HOSTNAME:process.env.HOSTNAME,})).PUBLIC_HOSTNAME in production.
