 I initially discovered this in FolderBrowserDialog where the problem was 
 only reproducable in some cases, however with the code from bug #81423 
 repro #2 it seems to always occur.  In FolderBrowserDialog one way of 
 enhancing the chances of hitting it, it to right-arrow expand a leaf node
 (!).

+This does not occur in MSFT's FolderBrowserDialog, but it *does* 
+occur in their TreeView impl.  (Presumably their FolderBrowserDialog 
+displays the respective Win32 dialog and is not .NET code using 
+SWF.TreeView).
+
+So do we fix the bug/feature in TreeView (a leaf node can be 
+IsExpanded)?  As a heavy keyboard user not being able  to close the 
+tree using the left-arrow key is a big pain.  However, perhaps 
+someone uses this odd behaviour as a feature -- expand a leaf node
+(!) then when you add children to it they appear.
+
+The other fix possibility is to have the left-arrow handing code 
+jump to the parent if either collapsed *or* has zero children.
