Emit adds generated code before file header/copyright comment

[mjbvz]

Steps to reproduce

Compile a ts file with a copyright comment:

/*---------------------------------------------------------------------------------------------
 *  Copyright
 *--------------------------------------------------------------------------------------------*/

export const a = 1;

Behavior with typescript@5.8

The generated helpers and module code is added after the comment:

"use strict";
/*---------------------------------------------------------------------------------------------
 *  Copyright
 *--------------------------------------------------------------------------------------------*/
Object.defineProperty(exports, "__esModule", { value: true });
exports.a = void 0;
exports.a = 1;

Behavior with tsgo

The copyright comment after the added code:

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
exports.a = void 0;
/*---------------------------------------------------------------------------------------------
 *  Copyright
 *--------------------------------------------------------------------------------------------*/
exports.a = 1;

I don't know how we are doomed in every version of TypeScript ever to have issues with the ordering of prologue directives and copyright headers.
