        //COMMENT 26.03.2020:
        // ERROR DESCRIPTION:
        //  see Ticket #1711, problem about icons not appearing:
        //    In the project that was sent to us on the 26th of March 2020:
        //    BasePage.xaml -> ItemsControl named "icSubNavigation" -> ItemTemplate Property -> DataTemplate with the key: dtSubNavigationIcon:
        //      Properly generated in C# but when translated into js, the first letter of the methods that are called is lowercased.
        //  I could not find the conditions nor the reasons for such a case to appear so I settled with the following workaround:
        // WORKAROUND:
        //  Create an additional private method with the same signature except with the first character of its name lowercased, that calls the original one.
        // NOTE:
        //  This workaround was used only for the methods that were in that specific case, so we might need to use it for other methods if other cases appear.
        //  Workaround currently used on:
        //      - INTERNAL_GetVisualStateGroups
        //      - RegisterName
        //END OF COMMENT

        // Note: this should be protected and the Control class should be abstract.
        /// <summary>
        /// Represents the base class for UI elements that use a <see cref="ControlTemplate"/>
        /// to define their appearance.
        /// </summary>
        public Control()
        {
            // Initialize the _templateCache to the default value for TemplateProperty.
            // If the default value is non-null then wire it to the current instance.
            PropertyMetadata metadata     = TemplateProperty.GetMetadata(this.GetType());
            ControlTemplate  defaultValue = (ControlTemplate)metadata.DefaultValue;

            if (defaultValue != null)
            {
                OnTemplateChanged(this, new DependencyPropertyChangedEventArgs(null, defaultValue, TemplateProperty));
