Only reproducible on X11.
STEPS TO REPRODUCE
1. add folder widget to desktop
2. click on the icon in the upper left corner of a folder inside the folder widget (popup view opens)
3. hover over a subfolder inside the popup
4. drag a file shown inside the popup view and try to drop it into parent view
it's impossible to drop the file into parent view because DnD operation is aborted when the cursor reaches the parent view. Watch the attached screen recording please.
