Edited Issue: Wizard Navigation CanSelect[Next|Previous]Page updating [17925]

Changing the bound values to CanSelectNextPage does not cause the Command.CanExecute to re-evaluate, so the button doesn't update until the Wizard Page is clicked somewhere.
 
The only way I got the NextButton to update after setting CanSelectNextPage = true was to use CommandManager.InvalidateRequerySuggested();
