Hey,
There is a bug in the tree and combotree components,
when there is a scroller in the tree, the selected node is not in the length of the node and it looks weird.
The same in the combotree.
Example:
http://jsfiddle.net/3L4ej4dx/62/Select the node with the text: "Microsoft Officeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee" and move the scroller.
Please check it out, Thanks!
