SUMMARY
Overview has a nice "Drag Down To Close" touch functionality. Desktop grid does not, but the label "Drag Down To Close" still appears, and the thumbnail still fades when dragged down.

STEPS TO REPRODUCE
1. Go into Desktop Grid (Meta + G or pull down with three fingers)
2. Drag a windows downwards to another virtual desktops (I have 4 virtual desktops in a 2x2 arrangment)

OBSERVED RESULT
Thumbnail fades and "Drag Down To Close" label appears

EXPECTED RESULT
Only thumbnail is moved, no additional effects.

SOFTWARE/OS VERSIONS
Operating System: openSUSE Tumbleweed 20260113
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.22.0
Qt Version: 6.10.1

ADDITIONAL INFORMATION
The code reponsible for the dragging down label and dimming is in "kwin/src/plugins/private/WindowHeapDelegate.qml". I couldn't figure out what the correct way to fix this would be, how that part can know it is in the grid effect. If someone wants to point me to how that QML module can find this out, I'll be happy to open a MR for it, though you might be faster at implementing that yourself.
