Module augmentation overrides interface rather than merge it

[supproduction]

Our behavior when augmenting a module interface, this interface fully overriding, rather than merging with them.

💻 Code

import { Price } from '@spryker-vsf/api';

declare module '@spryker-vsf/api' {
  interface Price {
    relevantGrossAmount: number | null;
    relevantNetAmount: number;
  }
}

let price: Price;

🙁 Actual behavior

🙂 Expected behavior

Merged interface

There isn't a Price definition in that library. Judging from the screenshots, it seems like you have a global type declared somewhere that you're re-exporting through a different module augmentation? In this case, you need to augment the global type instead.
