💻 Code

bugReportApi.d.ts

declare module '@bug/api/index' {

  export * from "@bug/api/miscFunctions";

}
declare module '@bug/api/miscFunctions' {

  export function myFunction(testParam: string): Promise<void>;
  

}

declare namespace bug.v0 {const api: typeof import('@bug/api/index')}

test.ts

bug.v0.api.myFunction('test')

🙁 Actual behavior

When I search for references to "myFunction", I only find the declaration in 'bugReportApi.d.ts', but not its usage in 'test.ts'. However, if I copy the contents of 'bugReportApi.d.ts' into a new file named 'bugReportApiC.d.ts' and search for references again, I find two declarations ('bugReportApi.d.ts' and 'bugReportApiC.d.ts') as well as the usage in 'test.ts'.

🙂 Expected behavior

The usage in 'test.ts' is found as reference.
