Creation of subcategories impossible after upgrading to 6.2.22
After upgrading to Typo3 6.2.22 it is impossible to create subcateogires to existing (sys_)categories.
Selecting a parent node in the tree select causes a yellow exclamation mark claiming something to be wrong and saving is not possible anymore.
After downgrading to 6.2.21 the error disappeared.

This problem only seems to occur with maxitems set.
In my tests (with sys_category) I encountered the following situations:
- maxitems: 1
1 item is selectable, but a exclamation mark appears when selected. When unselected, no item is selectable.
- maxitems: 2
1 item is selectable, if the tree is loaded with 1 item preselected 2 items are selectable.
- maxitems: 3
2 items are selectable, if the tree is loaded with 1 or more items preselected 3 items are selectable.
- maxitems: n
(n -1) items are selectable, if the tree is loaded with 1 or more items preselected n items are selectable.
(If the tree is loaded with some items preselected and all items are deselected n - 1 items are selectable).
