SUMMARY
In Grid Desktop view in Plasma 5.24 you could've start a drag outside all windows on one virtual desktop, and then move them all to a different one, switching the contents of those desktops.
It is impossible in Plasma 5.25. All windows from the source desktop are being dragged, but then are returned to that source desktop on mouse release.

STEPS TO REPRODUCE
1. Open 2 or more windows in one desktop.
2. Show Desktop Grid.
3. Click on that desktop outside any window.
4. Drag all windows to a different desktop and drop them.

OBSERVED RESULT
Windows are returned to the source desktop on mouse release.

EXPECTED RESULT
Windows should be moved to the target desktop.
Plasma <=5.24 behavior: the target desktop's contents should be moved to the source desktop (switching their content)

SOFTWARE/OS VERSIONS
Linux: Ubuntu 22.04
