QAbstractItemModelPrivate::allowMove not allowing a valid move operation

When using QAbstractItemModel::beginInsertRows it is not possible to move a row to the position below it (when having the same parent).

There seems to be a bug in the validity test : (in QAbstractItemModelPrivate::allowMove)
// Don't move the range within itself.
if (destinationParent == srcParent)
return !(destinationStart >= start && destinationStart <= end + 1);

Should be :
// Don't move the range within itself.
if (destinationParent == srcParent)
return !(destinationStart >= start && destinationStart <= end);
