instances of different classes with same name should not be treated as equal

🐛 Bug Report

Look at example. We have two different classes but with the same name Client.

test("", () => {
    const MysqlClient = (function () {
        return class Client{};
    })();
    const HttpClient = (function () {
        return class Client{};
    })();
    
    const clients = [new MysqlClient()];
    expect(clients).toEqual([new HttpClient()]); // pass
    expect(clients).toStrictEqual([new HttpClient()]); // pass, but should not
});

Expected behavior

expect([new MysqlClient()]).toStrictEqual([new HttpClient()]); should fail

Try it and see if it break any tests 😃
