import type { Metadata } from "next";

const metadata: Metadata = {};

export default metadata;

🙁 Actual behavior

Trying to execute the "Move to a new file" refactoring on the const metadata: Metadata = {}; line does nothing and an error is logged by the tsserver.

File text of /Users/daniel/Code/move-to-new-file-repro/src/next.ts:
    import type { Metadata } from "next";

    const metadata: Metadata = {};

    export default metadata;

🙂 Expected behavior

The metadata constant should be moved to a separate file

Additional information about the issue

This appears to be to some degree a specific interaction with the next module, as doing the same thing with a type from react works well. Downgrading to typescript 5.4 also works.
