When setting the Drag.dragType of a component to Drag.Automatic and then binding the Drag.active to the MouseArea::drag.active property (as instructed by the documentation), there is a warning about a binding loop.

rc:/qt/qml/externaldraganddrop/DragAndDropTextItem.qml:48:5: QML QQuickItem (parent or ancestor of QQuickDragAttached): Binding loop detected for property "active"

This is reproducible just by running the externaldraganddrop example in Qt Quick.

Tested on Linux/X11 and Linux/Wayland.
