A dock's content element is an object widget (Scene3DDockWidget, Scene2DDockWidget, …) when it is present and is not the PlotWidget's own element. Restore hands its tagName() to the object-widget factory as the "kind", so pj_plotting stays agnostic to specific scene families.

// <plot> element. Restore hands its tagName() to the object-widget factory as

bool isObjectWidgetElement(const QDomElement& element) {
  return !element.isNull() && element.tagName() != QStringLiteral("plot");
