Index out of range when an item contain more children than other items

[MrFahrenheit-55]

When adding a 2nd-level child to one of the list items, the lowest-level item cannot be moved to another 1st-level child. This causes an error of index out of range for the parent item to which the item is being moved.

• To replicate, add a 2nd-level child to one of the DragDropItems.
• Run the application.
• Try to move the 2nd-level child to another 1st-level child.
• The program will crash with an error.

@PhilipNell-258 would you be able to share the code of the widget you wrote, will save me a great amount of time. Nevermind if it's closed source, just trying my luck.
