Nope, it's not a bug.
The purpose of the hideRoot property is to allow you to simulate having
multiple root items. Root items do not, by default, display the open/close
icon. In the case of hideRoot being false, there is only a single visible
root item, and it does not show the open/close icon. When hideRoot is true,
then any children of the tree's root are virtual root items, so they too do
not display open/close icons.
All is not lost, however, if you really want to display the open/close icon
on root, or virtual root items. Simply set the tree's rootOpenClose
property to true.
