Issue

If too many windows are open like this

The window list starts to mix with the tray bar

Steps to reproduce

1. Add window list to the left, tray to the right
2. Open way too many windows

Expected behaviour

Applets not mixing, perhaps something like scrolling arrows or sth appearing and the overflowing entries hidden
