Comparing Properties with getters only

I have an immutable data structure defined as follow:

let DataStructure = function (name, description, imageUrl, linkUrl) {
    let _name = name;
    let _description = description;
    let _imageUrl = imageUrl;
    let _linkUrl = linkUrl;

    Object.defineProperty(this, 'name', {
        get: () => _name,
    });

    Object.defineProperty(this, 'description', {
        get: () => _description,
    });

    Object.defineProperty(this, 'imageUrl', {
        get: () => _imageUrl,
    });

    Object.defineProperty(this, 'linkUrl', {
        get: () => _linkUrl,
    });
};

Comparing to object instances with different values always returns true when it should return false.

Start by reproducing the comparison with two DataStructure instances whose getter-only properties return different values, then inspect the deep-eql comparison behavior involved. Done means those instances compare as unequal, with a regression test covering the getter-only properties.
