Dragging an event in month view does not work if dragging over another event (only empty spaces in the cell act as drop targets)
Affected version
45.0- 9ace504e
Bug summary
When dragging an event in month view not the whole target grid cell acts as a drop target as one would expect. The area covered by events in that cell does not accept the drop action. Instead only the remaining area in the cell accepts the drop action.
Steps to reproduce
Drag an event to another cell in month view that contains some event items. Release it above an event item.
What happened
When releasing the dragged event in another cell above an event item, the drop action is not performed and the intended move of the event to that cell fails without any indication.
What did you expect to happen
The whole grid cell should act as the drop target regardless of events below the pointer.
