sao adds a useless scrollbar to every view
As it can be seen on the demo server a scroll bar is present even though it is useless.
This stems from the computation occurring in set_treeview_height
which does not account for all the parent's padding-bottom.
Yet instead of fixing it through javascript it would probably be better to fix it using CSS as it would offload all the computation to the browser rendering engine. Having a declarative description of the interface is also probably a better solution.
