Research direction
Focus on the drag and drop addon logic for week and day views. The likely file is `addons/drag and drop/...` or similar. Examine how the 'Display dragged item in cell while dragging over' option is implemented for all day events versus hourly events. Look for differences in the DnD preview rendering logic between week/day views and month view. Check comments or linked PRs for prior attempts.
