GridView, (and TreeView which is based on it) internally uses a 
ScrollArea with Tracking = True. So it will always track the mouse even 
if you set Tracking = False on the control.

The documentation is not wrong per se, but when you use compound 
controls, the result can be unexpected.

GridView has to track the mouse because it changes the mouse cursor 
according to its location inside the view.
