Describe the bug
Dragging the first item to the second position in the same DropZone results in the item not reordering.

To Reproduce
Steps to reproduce the behavior:

  1. Go to https://blazor.radzen.com/dropzone
  2. Go to the first example
  3. In the "Not Started" drop zone, Click and drag Task0 onto Task1
  4. Observe the the list does not get reordered

Expected behavior
I expected the final state in the "Not Started" drop zone to be, from top to bottom, Task1, Task0, then Task2.

Screenshots

Desktop (please complete the following information):

  • OS: Windows 11
  • Browser Chrome
  • Version 134.0.6998.89

Additional context
Note that dragging in the opposite direction works as expected (e.g. dragging Task1 onto Task0 results in the order Task1, Task0, then Task2).

This is how the example is made, you need to drop to the previous item to reorder:
