Unexpected JTree node handle for node which can't be expanded appears
during initial JTree visualization. But after clicking the handle is
disappeared.

The following test example demonstrates the bug. After JTree visualization,
the tree contains three nodes "Root", "Children1", "Children2".
The node "Children1" has node handle which disappears after clicking it.
