I just now I set a breakpoint debugging and got the following value:
1. WpfApp. Window1
2. {. Microsoft VisualStudio. DesignTools. WpfTap. WpfVisualTreeService. Adorners. AdornerWindow} this show not to come out, but the debugging can see
3. WpfApp. Window2
4. {. Microsoft VisualStudio. DesignTools. WpfTap. WpfVisualTreeService. Adorners. AdornerWindow} to keep up with the same 2
5. WpfApp. Window3

2 and 4 of the Title value is empty, so there is no show, the great god can explain what this is
