.d.ts generation error behaviour

TypeScript Version: 3.4.2

Search Terms:
.d.ts; import path

Suppose I have following project structure:

The codes are emplaced at https://github.com/shrinktofit/ts-issue .

The generated .d.ts will be:

declare module "nested/shared" {
    export class B {
    }
}
declare module "nested/base" {
    import { B } from "nested/shared";
    export function f(): B;
}
declare module "nested/derived" {
    export function g(): import("nested").B; // LINE 10
}
declare module "nested/index" {
    export * from "nested/base";
    export * from "nested/derived";
    export * from "nested/shared";
}
declare module "index" {
    export * from "nested/index";
}

In line 10, the import("nested").B is an error with message nested is not a module; If I change it to import("nested/index").B, it's fine,

If I do not export nested/shared in module nested/index, generated code becomes:

declare module "nested/derived" {
    export function g(): import("nested/shared").B;
}

and the error disappear.
