TreeCtrl display bug [message #48108]

U++ has this nice feature when some item can't be displayed in a rect, a tool-tip appears with the full text.

This works fine with a narrow TreeCtrl where you add a very wide child. Mouse-over the child and it will popup perfectly.

But if I add a display to the TreeCtrl, the popup jumps up about 2-3 pixels vertically.

This is an incredibly serious mega bug Laughing

treetest::treetest()
{
	CtrlLayout(*this, "Window title");
	
	tree.SetRoot(Image(), "test");
	tree.SetDisplay(Single<ItemDisplay>());
	tree.Add(0, Image(), "aaaaaaaaaaaaaaaa");
	tree.Open(0);
}

Comment out the tree.SetDisplay(Single<ItemDisplay>()); and the tool-tip vertical jump is no more.

Test case attached.
