collapsing tree with sub trees open is not retained

[paulgevers]

In Ubuntu a bug [1] was reported against my package cacti. I believe the problem is in the jstree part of the code. The problem is that if you have opened several layers of a larger tree, and than close the tree at the root, the cookie plugin does not retain this state if you open some page.

I see this in my cookies:
All subtrees opened:
Name Cacti_jstree_open
Value %23tree_1%2C%23tree_1_leaf_8%2C%23tree_1_leaf_9

Closed at root:
Name Cacti_jstree_open
Value %23tree_1%2C%23tree_1_leaf_9

Where tree_1_leaf_9 is an element of tree_1_leaf_8.

Please feel free to request more information.
