Multi select parameter selection is not correct when the Kendo version 2020.2.617 is used.

As part of our security best practices, we need all components that we use to be Code Signed using SHA256.

When using the Report Viewer under WinForms, Print Preview allows the user to scroll through all report documents.  I.E., everything in the document map.  However, when using the Wpf version you cannot.  In the Wpf version, the user must use the Document map to select and scroll through each particular area.

For large reports containing multiple documents, this is tedious.  

Please make the Print Preview functionality for the WPF control match that supported by the WinForms control.
