domain property does not handle subdomain

Describe the bug

Hello,

I was exploring your project and I see that when a domain is added, subdomain are not handle.

In this image, any of these path are from unjs.io but from a subdomain (unhead I think).

Hey! Thanks for making an issue, this was something I was aware of but I didn't have any sites to test it out with.

Not exactly sure what the solution looks like but will start working on it soon.
