-/**
- * The Preview section of the Customization editor.
- * Displays the given view in a Tab Folder.
- * The preview uses the same Display Engine as the Property view, which should lead
- * to the same results, with a few exceptions :
- * - The Tab Folder has an Horizontal layout for its tabs, while the property view has
- * a vertical layout
- * - The preview is read-only : all actions are disabled. This means that it is
- * not possible to preview dialogs, for example
- * - The Enum and References fields are empty
- * - Some buttons may be marked as disabled, but will be available at runtime (Or vice-versa)
- * - The dynamic sections are always displayed
- *
- * The preview can be disabled for performance issues
