⏯ Playground Link

Reproduction: https://github.com/lamnhh/ts-expect-error-issue

💻 Code

There're 3 packages:

• package-a:

// @ts-expect-error global
export const SOMETHING: number = global.testNumber;

Anything that has an @ts-expect-error directive will work.

• a package-b that imports package-a
• anothe package-c that imports both package-a and package-b.

Install everything, then npm link package-b to use in package-c.

🙁 Actual behavior

Unused '@ts-expect-error' directive.

> typecheck
> tsc --noEmit

../package-b/node_modules/@lamnhh/package-a/index.ts:1:1 - error TS2578: Unused '@ts-expect-error' directive.

1 // @ts-expect-error global
  ~~~~~~~~~~~~~~~~~~~~~~~~~~


Found 1 error in ../package-b/node_modules/@lamnhh/package-a/index.ts:1

🙂 Expected behavior

tsc in package-c passes with no error.

Start with the reproduction repository at https://github.com/lamnhh/ts-expect-error-issue. Install the three packages, link package-b into package-c, and run tsc --noEmit in package-c to reproduce the unused @ts-expect-error diagnostic from package-a. Done means package-c type-checks without that diagnostic while the directive remains valid in package-a.
