svelte-kit package $lib reference conflicts with outer svelte project $lib

[thinkloop]

Describe the bug

I generated a package, copied it into another svelte project, but all the references to $lib inside the package look for files in the outer svelte project's $lib rather in itself - any way around that?

I get the error:

failed to load module for ssr: /src/lib/utils/fullscreen

Because the file is correctly at:

/src/MY-PACKAGE/utils/fullscreen

Reproduction

Make a project that includes some $lib imports.
Package the project with svelte-kit package.
Rename and copy the package into another svelte project.
Load one of the packages entry points in the new project.

Notice that the entry point is trying to find its dependency in the outer project's $lib folder rather than its own.
