Changes to the Window's content aren't applied by the refresh method, if the content isn't set up previously upon initialization or with the setOptions method.
The refresh method should correctly update the default content of the Window.
When attributes like Html class are added to the Html element from which the Window widget is initialized these attributes are applied to the Window's .k-window-content element instead of the outermost .k-window. This behavior is inconsistent with other web dev tools like Telerik UI for Blazor and the ThemeBuilder.
Window rendering must be consistent with other Kendo and Telerik suites.
