Describe the Bug

Since version 5.13.10, Astro.site is undefined in getStaticPaths().

This was last working in version 5.13.9.

This looks like the most relevant change in 5.13.10: https://github.com/withastro/astro/pull/14405/files#diff-6b0c74afa525663c451fc84841ec2040e7125f74e732da4ed7584b84896a759dL52

The linked repro is the blog example with pages/blog/[...slug].tsx] modified to demonstrate the problem. The example will run npm run build automatically.

If you run npm install [email protected] && npm run build the problem goes away.

What's the expected result?

It should work as it previously did, where Astro.site contained the URL configured in astro.config.mjs in a URL object.

Note: It’s possible that things other than getStaticPaths() are affected, that’s just where I noticed the problem.
