Incorrect export state of referenced but not directly exported namespaces/modules

[timocov]

Bug report

Input code

internals.ts

export namespace InternalNamespace {
	export type NSType = string;
}

export module InternalModule {
	export type MType = number;
}

export namespace ExportedNamespace {
	export type ENSType = 1 | 2;
}

export module ExportedModule {
	export type EMType = 3 | 4;
}

input.ts

import { InternalModule, InternalNamespace, ExportedModule, ExportedNamespace } from './internals';

export type A = InternalModule.MType;
export type B = InternalNamespace.NSType;

export { ExportedModule, ExportedNamespace };

Expected output

declare namespace InternalNamespace {
	type NSType = string;
}
declare module InternalModule {
	type MType = number;
}
export declare namespace ExportedNamespace {
	type ENSType = 1 | 2;
}
export declare module ExportedModule {
	type EMType = 3 | 4;
}
export type A = InternalModule.MType;
export type B = InternalNamespace.NSType;

export {};

Actual output

export declare namespace InternalNamespace {
	type NSType = string;
}
export declare module InternalModule {
	type MType = number;
}
export declare namespace ExportedNamespace {
	type ENSType = 1 | 2;
}
export declare module ExportedModule {
	type EMType = 3 | 4;
}
export type A = InternalModule.MType;
export type B = InternalNamespace.NSType;

export {};

(note that both InternalNamespace and InternalModule are exported but shouldn't)
