SUMMARY
when searching for a file, I used to be able to drag and drop files right from the search results into another app or the desktop or the panel. Now after update I cannot do it. No drag and drop operation would work for any type of search result, neither file nor applications. 
STEPS TO REPRODUCE
1. update to plasma 6.5.0
2. search for a file in Krunner
3. drag the file from the search result to the desktop or an open dolphin window

OBSERVED RESULT

Nothing happens. Drag and drop is not initiated

EXPECTED RESULT
The item should be dragged and the copy/move/link popup should appear.

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: 6.17.5-2-cachyos (64-bit)
KDE Plasma Version: 6.5.0
KDE Frameworks Version: 6.19.0
Qt Version: 6.10.0

ADDITIONAL INFORMATION
I have confirmed this is due to update by rolling back to 6.4.5 where it is working. And then back to the updated version where it again stopped working.

I've biscted this down to https://invent.kde.org/plasma/milou/-/commit/95f7c9fa805776123a763c08344665f3b272e87e which is surprising

Shadow Resultsmodel::getMimeData

Due to some unknown reason QML will not call the function
and just stops executing the qml function. As a workaround
shadow the function.
