Vetur seems to intellisense private properties in d.ts

Problem

I have an external library which is written in TypeScript. TS compiler generates .d.ts and .js files. and the entry is index.js.

When using this library, the intellisense suggests me not only public properties and methods but also private. I think vetur does not regard private in .d.ts.

Reproducible Case

I wrote a example.ts:

export class Example {
  doPublicly(): void { }
  private doPrivately(): void { }
}

example.js, which is generated by TypeScript compiler:

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
var Example = /** @class */ (function () {
    function Example() {
    }
    Example.prototype.doPublicly = function () { };
    Example.prototype.doPrivately = function () { };
    return Example;
}());
exports.Example = Example;
//# sourceMappingURL=example.js.map

example.d.ts, which is generated by TypeScript compiler:

export declare class Example {
    doPublicly(): void;
    private doPrivately;
}

Note that doPrivately method is marked as a private property.

Finally, I import this module in a vue component:

import { Example } from './example';

If I go to definition, VS Code opens example.d.ts.
