🕗 Version & Regression Information

This is the behavior in every version I tried, and I reviewed the FAQ for entries about triple slash directives.

💻 Code

module-one/PanelWindow.d.ts

declare global {
    interface CustomWindow {
        getSomething(): any;
    }

    interface Window {
        customWindow: CustomWindow;
    }
}

module-two/Class.ts

// <reference path="../../node_modules/storage-explorer/dist/PanelWindow.d.ts" />

import * as $ from "jquery";
import { IContextMenuItem } from "storage-explorer";

export interface ICustomType {
    someProperty: string;
}

export async function doSomething(args: ICustomType): any {
    const obj = await window.customWindow.getSomething();
    return obj;
}

🙁 Actual behavior

The triple slash directive is compiled to something similar to the following (note the casing is not preserved, even if forceConsistentCasingInFileNames is set to true):

// <reference types="module-one/customwindow" />

Because of this issue, I cannot compile on macOS. This is not an issue on Windows.

🙂 Expected behavior

I expect the triple slash directive in module-two/Class.ts to be compiled to something similar to the following (note the casing ought to be preserved if forceConsistentCasingInFileNames is set to true):

// <reference types="module-one/CustomWindow" />

Weirdly, this seems to have been implemented this way intentionally: #10340
