Password managers have seen their popularity skyrocket in recent years -- due in no small part to the steady pace of high-profile hacking incidents. Some in the online advertising game have figured out how to abuse password managers to track users online. If you are logged in, the page loads an invisible username and password form. In this case, unfortunately, it's doing so in a way that helps advertisers build a more detailed profile about you. Just change the settings in your password manager so that it doesn't automatically log you in when it detects a login form.
