The combo box does not size the scrollable area of the box to fit within the visible area of the browser. This means that when you open the list, you can have to scroll the page just to see the other end of the list. Especially annoying if you have a lot of items in the combo box since it can make some items inaccessible without resizing the browser window.
It also doesn't detect the best direction to expand the box based on proximity to the browser window edge.
This is with EnableScreenBoundaryDetection set to true.
