Visual demonstration of the issue.

SUMMARY  
After the latest KDE Neon update, which was supposed to fix issues related to
moving tabs/apps in the Task Manager with icons, a new issue appeared in the
Virtual Desktop Manager. When trying to move an application window from one
virtual desktop to another, the behavior is inconsistent. Sometimes, during the
drag-and-drop action, the window gets stuck between two desktops and returns to
its original position instead of moving to the intended virtual desktop. Other
times, it works as expected.  

STEPS TO REPRODUCE  
1. Open multiple virtual desktops.  
2. Try to move an application window from one virtual desktop to another using
drag and drop.  
3. Observe the behavior when crossing between desktops.  

OBSERVED RESULT  
- The window sometimes gets stuck between two desktops and returns to its
original position instead of moving to the intended virtual desktop.  
- In some cases, the movement works correctly, but the issue occurs randomly.  

EXPECTED RESULT  
The application window should move smoothly from one virtual desktop to another
without getting stuck or returning to its original position.  

SOFTWARE/OS VERSIONS  
- Operating System: KDE Neon 6.2  
- KDE Plasma Version: 6.3.0  
- KDE Frameworks Version: 6.10.0  
- Qt Version: 6.8.2  
- Kernel Version: 6.8.0-49-generic (64-bit)  
- Graphics Platform: Wayland  

ADDITIONAL INFORMATION  
This issue appeared after the latest KDE Neon update, which was intended to fix
the movement of tabs/apps in the Task Manager with icons. It is possible that
both issues are related. A video demonstrating the problem is attached for
better understanding.
