Taskbar shown when child window closed when IgnoreTaskbarOnMaximize=true

[gerthermans]

This zip file contains a simple c# project presenting the issue.
Steps to reproduce:

1. Start the project
2. Notice task bar is hidden (IgnoreTaskbarOnMaximize = true and WindowState=Maximized)
3. Click show window button to open child window
4. Close child window with close button
   Expected result: Task bar is still hidden
   Actual result: Taskbar is shown

@gerthermans Thx for the sample. Just tested it on my home pc and can't reproduce it with Win10 1709. Seems like the main bug is fixed on the OS itself. I get your issue with 1607 and 1703 too.

[gerthermans]

The issue still occurs with Win10 1709 when the child window is maximized and also has IgnoreTaskbarOnMaximize = true.
I've added an adjusted sample to show the issue.
Also in this sample I did add some code in comment in the closed eventhandler of childwindow.xaml.cs which can be used for a fix for now, but would be good if this issue could be fixed more generally in the next version.

/cc @batzen This is still an issue also with the latest ControlzEx v4.0 alpha

Will have a look at this in ControlzEx.
