Tree is completely re-loaded on every OID update

[danielmarschall]

Today I noticed something very annoying.

Reproduction:

1. Open an OID which requires a lot of nodes being opened in the tree
2. Update the OID
3. The tree on the left will reload, and the OID on the right side will also reload
4. The tree will slowly open step-by-step (using treeload ajax.php)
5. After the tree has been fully opened, the node will be selected and on the right side, the OID will be opened.

There are two problems:

1. During that very slow treeloading, the nodes are not automatically opened for some reason (they only get opened when you open the OID using the goto-box, but not when you updated an OID)
2. It should not be that the OID is re-reloaded once the tree-loading is done. Because while the tree is loading, I am already editing a different OID, and then my changes get lost due to the unnecessary reload!
