Sets & Groups won't mousewheel scroll


The Sets & Groups page won't scroll with the mousewheel unless you hover your mouse directly over the scroll bar. At this point, if you've already moved your mouse into this very specific narrow area, you might as well just click and drag the scroll bar directly. Very annoying if you have a lot of groups. This is in both "Text and Icon" view and "Text Only" view.

The photo queue, on the left side of the screen, scrolls fine with mousewheel, so i know it should be possible.
