/* Qt has a recent bug (2023, https://bugreports.qt.io/browse/QTBUG-100128)
* where the items disappears in certain conditions when drag and dropping.
* Here we prevent the situation where this happens.
* 1 - If the item is dropped on the item below such that the item doesn't move (ie superior half of the below item)
* 2 - The item is the last one and user drop it on the empty space below.
* In both those cases the item widget was lost.
