Bug explanation

Steps to reproduce

Used a hyper-v VM running Win 10 21H2 build 19044.1466 + the MainDemo.Wpf app latest commit 607ee6a:

1. Transfer the MainDemo.Wpf app to the VM
2. Open the MainDemo.Wpf app and navigate to Dialogs
3. Click "Run Code" under Sample 3
4. While the dialog is visible, close the window which disconnects from the VM but leave the VM running
5. Reconect to the VM and login.
6. Notice that the dialog is no longer visible, the obscured background of the app is still greyed out and present, and nothing in the app being overlaid by the DialogHost responds to user input.

Screenshot for step 3 above:

The short story of them problem seems to be: If the user gets disconnected from a remote session AND a dialog is visible when the disconnect occurs, then the user on reconnect will see a greyed out screen and no visible dialog on reconnect. Anyone ran into this and is there a known workaround?
