You *do* need to set the height, at least, to create the vertical scrollbar. So what size do you want to constrain it to? Can you show an example of a page where the tag list is too long that you want to add the scrollbar to?

Maybe this page?

Add this to the topic-tags CSS right where you added the overflow: auto

height: 110px;

That will make it about as tall as the information to the left (at least on this page, with the amount of information there.)
