MouseArea not working after Drop

I extended Qt's draganddrop example, by giving the icons a MouseArea. I want that MouseArea to perform an Action onPressAndHold, but only if the item is not being dragged. This MouseArea works at startup, but if the item is dropped after a drag, the MouseArea is not responding to my clicks anymore. However, after e.g. 5 clicks, it starts responding again. This seems like a bug to me.

To reproduce this behaviour, execute the attached file, and click on the icons before, and after dragging. If a click was successull, you will see an output via console.log
