/**
 * Makes an externally-hosted Staffbase widget usable in the classic page editor.
 *
 * The classic editor runs the bundle in the top window but never defines the
 * custom element inside its tinymce canvas iframe, so placed elements stay inert
 * there and have no edit affordance. Call this once from the bundle entry (after
 * defineBlock). It watches for tinymce canvas iframes and, in each, defines a
 * preview element that renders the widget's editor view (with a limited-editor
 * warning) and opens the widget's config form on double-click, persisting edits
 * via Staffbase's classic-editor save model.
 *
 * No-op outside the classic editor (?isClassic=true) and on cross-origin iframes.
 * @param {ClassicEditorSupportConfig} config - The widget's support config.
 * @returns {void}
