Add Scrollbar to Password Input List for F-Secure Key

As you can see, the username and password input is in the bottom-right of the browser window (Google Chrome), and my password required is not visible due to being cut off. Even if I move down the list with the down arrow key, I cannot see which password I am selecting. Please add a scrollbar to the password list to be able to select any password on any part of the page. How has this not been implemented sooner?
