Reexported types are emitted as actual modules in js files generating runtime errors.
Problem occurs in both commonjs and esmodule.

Reexported types interfaces dts
Code
// types.d.ts
export type Foo = 1;
export type Bar = 2;
//--------------------------------------
// index.ts
export * from "./types"

Expected behavior:
Don't emit types reexports
Actual behavior:
commonjs
